    Something special was happening here - it sounds as if the potential victims were being approached in order to identify targets.

    You're getting two different incidents confused:

    - In Palo Alto a bunch of burglars was working the street. They skipped our house (and the ex-cop's).

    - In our current town (which I will not name) there are a couple (recently moved-in) gang houses a few blocks away. This being a well-established neighborhood near the town's Jr High and elementary schools, when something goes down the cops get called. So the gangsters are trying to establish themselves as someone whose activities should not be reported - by intimidating the locals. Bumper stickers alone weren't enough to repell them. (Probably thought they were on MY car, and that the wifey would be an easy, and undefended, mark. B-) ) But they got out-psyched by my wife the personal-protection instructor.

    A lot could be gleaned from a brief conversation - body languages and nuances in your reply would often expose weaknesses - sort-out the easy pickings. The fact that the answer was a credible "you won't get away with that" - "attack me and that is likely the last attack you make" probably made you appear a less desirable target. I'd wager that you wouldn't need to own any weapons in order to achieve the same effect. I suspect that you avoided trouble by old-fashioned confidence...

    I, on the other hand, wouldn't expect a bluff to be as effective as a pat hand. The crooks who specialize in intimidation are often very good at reading body language, and other signs of real participation in the gun culture (like vocabulary, word choice, attitude, catchphrases, etc.). Also: Range time makes you respond to stress by calming down and steadying (to the point that your usual gun hand(s) become rock-steady and your breathing slows), rather than becoming excited and shaking. This is VERY visible to somebody who's trying to "read" you.

    You MIGHT be able to get away with a bluff. But I wouldn't expect it to work. More likely it would lead to escalation, as your bluff is called.

    Confidence comes from KNOWING you're capable. Crooks deal with pretenders all the time, and learn to sort out who's for real and who's not.

    I might even go so far as to suggest that attempting to use a gun would likely have increased your personal risk... but all is fair during the initial bluff eh?

    Huh?

    You do NOT pull out a gun in such a situation. We're not talking the knife in the hand or the fist in the face here. We're talking a set of careful, calm, "questions" by the intimidator - designed to be plausibly deniable as mere curiosity rather than an intimidation attempt.

    Actually showing a gun is strictly for a situation where the bad guy has made it clear (to any "reasonable and prudent" person) that he's in the process of an actual attack, the attackee is in IMMEDIATE fear for his/her life-or-limb, and that the attackee WILL shoot if ONE MORE MOVE is made.

    Actually showing the gun in such an initial-contact by a gangsta just shows you DON'T know what you're doing (and that you have a gun to steal, which will probably be improperly secured later.)

    I take issue with shooting to injure, though. If at all possible to disable without taking life, one should try.

    Rule is "shoot to stop the attack". Once the attack stops you have to stop shooting. (Again: In most jurisdictions.)

    Humans are very tough. Stopping an attack in progress will do serious damage. Can't be helped.

    Aiming "to disable" is VERY HARD. Doing it when you're actually being attacked, and SUCCEEDING in hitting what you're aiming at, is virtually impossible. The "stop" targets are large and move almost in a straight line. The "disable" targets are small and rapidly moving in varying directions. You'll miss. Count on it. And if you miss you are very likely to be injured or killed, IF the guy was really attacking. So it's not someting you attempt when you're being attacked and really ARE in fear of life-or-limb. That's why shooting to disable is, in many places, considered evidence that the shoot was premeditated assault rather than self-defense.

    "If you had the leisure and presence of mind to aim to disable, why were you shooting at all?" Shoot to disable and you'd better have a good answer for that question when it's asked, first by the police, then by the prosecuting attorney.

    Killing someone because of trespassing? Someone that's almost surely unarmed!? That's the last solution I would've chosen, if at all.

    "Because of tresspassing". Not even "because he tresspassed". Already your bending the language to avoid putting the responsibility where it belongs - on the person who chose to "tresspass", almost certainly as the first step of committing a more serious crime - like car theft, vandalism, rape, burglary, etc.

    But you DON'T shoot somebody who's just tresspassing. You warn them off (or in some jusisdictions, if you have evidence of a lot more than tresspass, demand they stay put with their hands where you can see them until the police arrive to sort it all out.)

    If you'd actually TAKEN the course recommended by the original poster, you'd know that.

    As for "unarmed":

    If you point a gun at somebody and demand that he leave, and he comes at you instead, either he's armed or plumb crazy and thinks he's strong enough to take you DESPITE the gun. Either way a "reasonable and prudent person" would believe that he's about to take "serious bodily harm" unless he does something.

    THAT's the legal standard for firing.

    But not for KILLING. You fire to STOP THE ATTACK. Maybe one in four he dies. His tough luck.

    If you're a 120-pound skinny (or 250-pound fat) nerd and he's a 280-pound muscle-bound felon who spent two years pumping iron in stir until they let him out last week, he doesn't NEED a weapon to take you. But that doesn't mean he doesn't have one. Him coming at you after you point a gun at him and tell him to leave is a VERY strong hint.

    Fortunately, most crooks are smart enough to realize that if you've got the gun pointed at them it's time to leave now. So you almost NEVER have to shoot.

    But (like seatbelts, fire extinguishers, and armies) you have to be READY and WILLING to use them when they're needed or there's no point in having them in the first place. And some human predators are good enough at reading your resolve that they'll know if you're NOT willing to shoot - so you have to be willing.

  8. Rifles, shotguns, pistols, etc. for home defense. on Home Defense, Geek Style? · · Score: 4, Insightful

    I tend to agree with you but how is a rifle which fires a more powerfull cartredge offer a greater opportunity not to kill?

    Compared to a shotgun? It's the difference between one small hole and a saucer-sized circle of nine big ones (or one saucer-sized hole, depending on the shotgun load).

    But it is hard to generalize, since rifles and their ammunition come in a wide variety of calibers, energies, and bullet expansion characteriesics. Just remember that the shotgun shoots more bullets at once, propelling them with more total powder, to get the general idea. One shotgun blast is like emptying the magazine of a rifle.

    Downside to both rifles and shotguns: They're long (even the "short" ones). If the bad guy gets within arms-reach (which he can do from across the room in under a second) he can get behind the muzzle and you're toast. A pistol MIGHT be usable even while he's wrestling with you or knifing you.

    That time issue, though, is why, as part of your training, you learn a two-sided coin:

    Heads: You NEVER point a gun at anything you aren't willing to destroy.

    Tails: If you are pointing a gun at the bad guy, you ALREADY DECIDED that you're justified if you use it and you're going to pull the trigger if he makes ONE MORE MOVE toward you.

    Once the gun is pointed you don't have time to wrestle with your conscience if it turns out you have to use it. So get that over with (and the safety off) BEFORE you point it.

    Don't try to wing him, either. Not only is it a bad idea self-defense wise (it's hard enough hitting him near the center of the torso in a stressful situation), it's also evidence that you didn't think deadly force was necessary (so why did you use it?) This can turn a justifiable homicide into assault with a deadly weapon once it gets to court.

    Either you fear for life-and-limb (of yourself or someone properly under your protection, like a family member or guest) or you don't. If you do, you are justified in using deadly force - and the bad guy gets to take his chances (about one in four) of dying as a result of his criminal decisions. If you don't, you're not justified in shooting, or pointing, at all. (At least in most jurisdictions. Some, like Texas, let you defend your home, car, etc. Others still have a "fleeing felon" rule - or a judicial interpretation (Oregon) that you might fear the crook is running out to his car to get some firepower or reenforcements. Still others (like MA) require you to flee if you physically can, even at home, abandoning the baby and risking a shot in the back.)

    For myself:

    Home defense at the townhouse: 12 guage shotgun with #40 birdshot. Quite as effective as 00 buck at in-house distances, but passing through a copule layers of drywall will slow it down enough that it won't kill the neighbors.

    Ditto at the country house: 12 guage w/00 buck. (Closest houses are over 1/10th mile away and the siding is wood over wood, shots where a good guy is behind the bad guy and an interior wall virtually impossible.)

    Personal carry: 38 special airweight for cities, 45 ACP backup for country hikes (where I might have to deal with a coyote, mountain lion, bobcat, or bear). Will probably switch to 357 magnum now that NV alows more than two on the license, since slide-actions are more often problematic in a pinch. Both only where it's legal, of course. (I.e. in NV but not CA.)

    And of course the personal carry pistol can be used for home defense if you happen to have it handy - like when you've just arrived, are unloading the luggage, and haven't pulled the shotgun out of the safe yet. A likely time for a bad guy to come at you, when things are open and you're distracted.

Even to get things prototpyed typically takes a seed round and a "series A". Then B for full-blown development of a manufacturable product and C for product introduction and initial production ramp-up. A software product might get by with maybe one or even two rounds less. But given the need to set up a support and marketing organization - and to eat while burning the midnight oil - it's still not going to happen without serious money input.

    So if you're not personally rich you must go to someone else for your miney. Maybe an "angel" for your seed, but for sure the venture capitalists for your funding rounds.

    Yes you can still innovate - if you're one of the three-or-so founders forming the core archetectural and business team. But the people who would become the high-skill early hires, the mid-to-high-skill line engineers, and the "dedicated support staff" get to keep flipping burgers. Those positions will only be filled outside the US. Not because that would make real business sense. But because if you don't build your company that way you don't get the money you need to build it at all.

    And it will continue in this vein until enough vultures get burned in India (or wherever) that they all flock somewhere else. And after three or so tries, it will dawn on some of those who still have some funds left that maybe the US workers really ARE a good price-performance tradeoff.

    It's starting to happen in India. SO many outsourcing operations have been directed there by the herd-mentality pointy-hairs that the good, and the mediocre, engineering talent has all been snapped up (and bid up), leaving newcomers with a choice between taking the new grads and dregs or paying near-US-level prices to hire talent away from other operations. But you KNOW the vultures will try it again in a couple other places before the light finally dawns.

    In particluar, it appears that software in particular doesn't require patent protection at all. By the time it can be reverse-engineered and cloned, the original product (if it was worthwhile at all) has typically made back its development costs and made a massive profit to more than adequately reward the developers and investors for their hard work and risk-taking. Further, at that point the originator is the dominant player in the self-created market, and it takes a major technological leap to displace him.

    2. Patents are too easy to get. That is a particular problem with software.
