Slippery Slime Developed to Control Crowds

powlow writes "Southwest Research Institute (press release )developed a non-hazardous chemical spray system that spreads a highly slippery, viscous gel (which the lab designated a "mobility denial system" and dubbed "banana peel in a can") to inhibit the movement of individuals or vehicles on treated surfaces. Marines Corps believes it can be used for crowd control. (Defense Technical Information Center's PDF Report) In tests, volunteers attempted in vain to walk across a lawn sprayed with the slime, and in fact, had they not been safety-harnessed during the tests, many would have broken bones."

    As one involved on the fringes of law enforcement, I find this interesting in many ways. Currently, there are several options should a law enforcement officer wish to disable a single person:
    • Rubber Bullets / Bean Bag Rounds (can cause permanent damage, although if used properly rarely do)
    • "Pepperball"-type products. Fabrique Nationale has a new one on the way that is a purpose-built CO2 launcher (not a paintball gun) that shoots chemical mace, a hard-nosed projectile, and my personal favorite, a "malodorant" that causes the target to puke himself into giving up
    On the mass-of-people front, there isn't much to do besides tear gas grenades, or making an example out of some with the above options. This gel could prove to be very useful, especially as a deterrent BEFORE riot-type activities start (anyone for slicking down the sidewalk in front of the WTO meeting?) A few skinned knees are MUCH more desirable than broken teeth cause some cop got jostled when he fired the rubber baton launcher.

  3. dihydrogen monoxide is chemical warfare by Crazy+Diamond · · Score: 5, Informative

    Being slimed is inhumane but rubber bullets are not? And since you are so anti-chemical weapons, maybe you should've read your own link where it refers only to chemical weapon use in warfare. Being slimed refers to riot control which is approved given proper listing of chemicals used. In fact do you understand all implications of the treaty. Why isn't dihydrogen monoxide considered a chemical weapon? Discount the fact that you're wrong about slime, a blast of good old dihydrogen monoxide has temporarily incapacitated many a charging rioter. It has been used for crowd/riot control for ages. Under your (wrong) interpretation that would be illegal under the Chemical Weapons Convention.

    From YOUR link:

    1. "Chemical Weapons" means the following, together or separately:

    (a) Toxic chemicals and their precursors, except where intended for purposes not prohibited under this Convention, as long as the types and quantities are consistent with such purposes;

    (b) Munitions and devices, specifically designed to cause death or other harm through the toxic properties of those toxic chemicals specified in subparagraph (a), which would be released as a
    result of the employment of such munitions and devices;

    (c) Any equipment specifically designed for use directly in connection with the employment of munitions and devices specified in subparagraph (b).

    2. "Toxic Chemical" means:

    Any chemical which through its chemical action on life processes can cause death, temporary incapacitation or permanent harm to humans or animals. This includes all such chemicals, regardless
    of their origin or of their method of production, and regardless of whether they are produced in facilities, in munitions or elsewhere.

    (For the purpose of implementing this Convention, toxic chemicals which have been identified for the application of verification measures are listed in Schedules contained in the Annex on
    Chemicals.)

    From YOUR link:

    5. Each State Party undertakes not to use riot control agents as a method of warfare.

    From YOUR link:

    7. "Riot Control Agent" means:

    Any chemical not listed in a Schedule, which can produce rapidly in humans sensory irritation or disabling physical effects which disappear within a short time following termination of exposure.

    From YOUR link:

    9. "Purposes Not Prohibited Under this Convention" means:

    (d) Law enforcement including domestic riot control purposes.

    As for combat uses... if they can hit an adversary with foam or slime, why can't they equally easily hit them with a bullet or a bomb?

    I just thought you might want to reread this sentence on the definition of a toxic chemical: "Any chemical which through its chemical action on life processes can cause ..." With slime, which chemical action on which life process causes temporary incapacitation?

    If you say it's a physical effect causing the normal life process of walking to result in incapacitation, why are lead bullets not considered chemical weapons? I'd say a bullet piercing flesh is a very chemical action. Any good chemist could explain to you the atomic chemistry of why the lead bullet traveling at considerable speed can pierce a less rigid entity such as a human's skin and internal organs.

    I discussed this at length in a rather old post... Basically, the Marines have as part of their duty guarding things like Embassies. So when the mob comes to torch the place, you don't want to just open up on them with your SAW gunnners and grenadiers. Tear gas (CS gas, really) isn't easily controlled; a good wind and its more or less gone. Other methods (riot guns for example) may provoke a more violent response (they hear BANG! and see people go down; the Americans are killing everyone!) and generally speaking, don't work against crowds (one shot one bad guy). Night sticks put you in harms way BIG TIME. So the Marines are looking for ways to supplement their arsenal because the only other option is to just kill the bad guys.

    So how is this "non-hazardous"? Are they going to hand out safety harnesses to crowds before they get sprayed with slime?

    The mass anti-corporate globalization protests over the past three years have seen the development of some fairly effective, DIY defense tactics against "non-lethal" crowd control measures.

    Tear gas and pepper spray? Bandanna soaked with cider or vinegar on the low end, gas mask on the high end, full-coverage clothing. Gas masks are especially preferable if the riot troopers are especially teargas-happy.

    Batons and rubber bullets? Shields, helmets, padding, and loads of backup.

    I haven't learned of any reasonable defenses against taser attacks yet, and they have been used on occasion (I'm specifically thinking of a few incidents during the Ottawa G20/IMF/WB protests last November). Something would be needed to block the electrodes; hockey pads, perhaps? Sometimes, dogs will also be used (again, Ottawa G20), and there's just not much you can do when a well-trained Fido decides to gnaw on your leg. Again, padding, perhaps sports pads.

    This stuff? Skis, high-traction footwear, maybe carry something to dissolve the slime. Perhaps sandbags might become the next big thing at protests?

      Rather than block the electrodes, it might be better to short them out. Clothes soaked in salt water might do it, but a better choice would be metal or carbon fibre cloth.

      Sounds fine, as long as there are intervening layers of clothing between the shorting surface and your skin. I'm just not comfortable with something conductive being in contact with my epidermis, which may expose my lack of hard knowledge regarding electrical transmission...

      As for Fido, carry a Taser yourself. A disposable Flash camera can easily be adapted :).

      Actually, I'd prefer to avoid harming the dog whenever possible. The idea is defense and resistance, not attack and harm. Beyond those who engage in property destruction as a symbolic protest against the concept of private, exclusive property[0], nearly all protesters prepare to defend against police attacks, not attack the police themselves. Weapons are generally limited to the really hardcore militants, and their target is property, not people.[1] There have been some funny incidents where police displayed an array of "weapons" at press conferences, and journalists helpfully pointed out their gas masks and microphones confiscated earlier in the day.

      [0] Before anyone attacks; I find that smashing windows of major franchise/chain restaurants and shops just frightens the people demonstrators try to reach. Symbolic, yes, effective, not if effective means exposing people to new ideas. Or, as one anti-capitalist militant said (I forget his name right now), "It's not enough to smash a McDonald's window. Then you have to go inside and organize."

      On the other hand, I wonder how much more coverage, and what kind of coverage the recent WEF protests would have received if a few windows had been smashed, or even if demonstrators resisted NYPD arrest attempts. Many demonstrators who did nothing to break any laws were grabbed; one IMC correspondent was tackled and arrested while calling in a live report on his cell phone. As it was, the New York media prepared the city for civil war, then declared the protests a failure when riots didn't break out. Damned if you do...

      [1] This is true for North American protests. Certain protests in Europe have seen more militant actions; Prague and Genoa in particular featured attempts to break through police lines and offensive actions against riot cops. From what I know, Genoa was a massive aberration, one step short of a worst-case scenario for cops and protesters alike. While there was a sizable militant anti-capitalist group that engaged in property destruction and rioting, claims have surfaced of British and Italian fascist skinheads joining forces to stir things up. A few scattered reports also surfaced of "black blockers" passing through police lines unhindered, or meeting outside police stations without harassment, but the veracity and meaning of these reports is still hotly debated among activists. For the most part, Western mass protests are noisy, but peaceful affairs where the violence comes from a few hotheads, and the police.

      If you think the above claim is paranoid, dig up info on protests last summer in Barcelona related to the aborted World Bank meeting there. Two undercovers sidled up to the main Saturday march, attempted to start a brawl by fighting each other, and when demonstrators tried to break the cops up, uniformed police took the opportunity to attack and arrest people. Pictures later surfaced of "black blockers" posing with uniformed police on lawns before the demonstrations. Not to mention the attack on a spokescouncil meeting after the main march. The Ottawa Citizen published a series on RCMP infiltration and surveillance of political groups across Canada, which may no longer be online. It's only paranoia if they're not watching you...

      Yes, I'm an anarchist whackjob. No, I'm not a Black Blocker. Yes, I think Bush is nuts. No, I don't like bin Laden either.

    "Riots, protests, noncombatant evacuations, and sanction enforcement are just a few of the situations where this kind of tactical barrier would be most useful," says Capt. Andrew B. Warren, MDS project officer for Marine Corps Systems Command, headquartered in Quantico, Va.

    ...

    "The concept of employment for this system is to be part of a barrier or obstacle plan that will provide stand-off distance and force protection for U.S. military personnel," says Warren. "The MDS will be applicable in many different missions to include checkpoint operations, denying avenues of approach, and dealing with confrontational crowds."

    Not for crowd control. Not for encouraging dispersal. It's purpose is as a quickly deployed barrier against incursion by people or vehicles that they need to be kept out.

    And people get injured in riots and attacks all the time. Current old-fasioned non-lethal weapons are, in fact, _designed_ to injure, in preference to killing outright. There are some circumstances where you have to stop people from doing violent things, particularly in millitary situations.

    By giving the rioter the point where they can not longer pass. the rioter has to learn how to make there statements better know.

    If anything this is the best thing in the improvement of free speach, since you can no longer pass a certain point, you must find a way to overcome. Now the protesters will learn marketing ( I like those anti-smoking ad's myself and i'm a smoker who is trying to quit ), how to deal with the press better.
