Retail Theft Detectors and False Alarms?

NichardRixon asks: "All too often I set off the 'shoplifter alarm' when leaving a major department store in my area, after purchasing OTC medicine. Even though I make a point of watching the cashier 'clear' the boxes, it is evidently an imprecise process. As often as not the alarm goes off as I leave, and the security person wants to look through my bag and compare what's found with my reciept. People passing by give me the evil eye, evidently assuming that I've been caught stealing. This has happened so so many times that my new policy is to refuse to stop for the search, telling the gaurd that they will have to tackle me, and of course they just let me go. Shouldn't stores be required to use more reliable equipment?" What's worse is that there are many retailers that are just plain apathetic to the alarm. What's the point of having these detectors if all they are is continuing source of false alarms? What good will they be when they catch a real theft in progress and no one reacts properly because of their questionable history? "It happened to my wife the other day, however, and she felt as though she had no choice but to wait several minutes, embarassingly on display to other shoppers, for the arrival of the manager. I was wondering if other Slashdot readers have been having similar experiences and if so, how they deal with them."

      I was doing some research and carried my PowerMac bag with me for obvious reasons. When I was leaving the security system went off. The staff sort of freaked. I had to empty my bag and add one item at a time back into it to see if the alarm got set off by that item.

      The EAS systems in use by most retailers use a small security tag composed of two magnetized metal strips inside a plastic package. Contrary to popular opinion the following items will not set off the alarms:
      • steel-toe boots
      • cellphones
      • magnets
      • digital watches
      • eel-skin wallets
      (Note: Eel-skin wallets aren't made from the skin of eels, they're made from the skin of hagfish.)

      What will set the system off are any of the following:
      • security tags in product
      • security tags stuck to soles of shoes
      • security tags stuck in shoes/purses/wallets by the manufacturer
      • certain celestial alignments
      • the 'wee folk'

      The alarm system I have at my store goes off most often when someone is coming in from the mall. Typically they've purchased something from a retailer who doesn't use the system, and the manufacturer ever so helpfully stuck a tag in the box before shipping it to the retailer. Cellphone kiosks, Radio Shack and Sears are the biggest offenders (they're not doing anything wrong, the manufacturers are just being too helpful). Outgoing alarms are less frequent, and are usually caused by a failure of the equipment to collapse a tag properly.

      How do we handle it? Each employee has been instructed to handle an alarm in the exact same fashion. On an incoming alarm, we ask the customer to come to the register and explain that something they bought somewhere else wasn't handled properly. We make sure everyone can hear as we explain that it happens all the time, and we're helping them out by making sure the alarms don't go off in other stores as they continue to shop. I've only ever seen one customer refuse or get upset about this.

      On an outgoing alarm we laugh and apologize for what obviously was our error. We screwed that one up, it must be our fault, because there's no way we'll consider that someone might be stealing from us. Of course we don't say it this way, but that's the image we project. You'd be shocked at how quickly a thief will confess or, more often, dump whatever they've stolen behind them somewhere, when you respond to the alarm.

      The big thing we do is respond to the alarm. We don't ever embarass our customers (or the visitors who didn't buy). If there's any doubt or people don't want to stop, we let them go. A real shoplifter will dump the product, confess, or take off running.

      Of course, this has given rise to what I tell customers as they're leaving: "Thanks for coming by. I deactivated the security tag, so the alarm shouldn't go off as you're leaving. But if it does, do what everyone else does ... just run."

      My customers love me. I have no idea why. I've gotten standing ovations from them. Weird.

    Is it maybe some kind of insurance policy that is cheaper if they have these anti-theft things? I too have noticed how most store employees don't even pay attention when they go off. The customers get far more upset than the employees do.

    There was a time awhile back when I used to set these things off almost everywhere I went. Eventually I started to remove one item each time I went to the store. First it was my keys, then my cell phone. The alarm would still go off. Then I tried leaving my wallet in the car and just carry in the cash I needed. Lo and behold, the alarm didn't go off! So after some careful investigation I found that my wallet still had the anti-theft sticker tucked inside an unused pocket. What was strange about this is that the alarm problem had only started recently even though the wallet had been with me for years.

    After thinking about it a bit, I determined that the problem had to be caused by either one of two likely possibilities (or a combination of them). The most likely explanation is that the old security key card I had had was blocking the anti-theft device. I didn't connect to the two immediately, but the problem of the alarms going off began to occur about the time I turned that badge in. The other possible explanation is that somehow the anti-theft device was re-activated. I'm not even sure if that's possible or not, but I had the wallet before I got the job that required the security key card and never had any problem going through those detectors.

    In any case, after removing the old anti-theft sticker, I've not had any problems with those devices. So if you're one of those who keeps setting them off, you might have a look for something like this. :-)

    2. In any case, in order for it to be a "felony arrest" you would have to have been arrested and charged with Theft in the First Degree or some other felony, which you weren't. (I cited an Oregon statute because in a later post you mentioned that it was a Fred Meyer's in one of Oregon's larger towns - I'd be willing to bet it's Eugene.)

I can only think of a few reasons that "it's not likely [you'll] succeed". One is because you have other arrests where you were booked and possibly convicted that you didn't mention in your story. It's also possible you gave the cops a hard time (yelling things like "fuck you - I didn't do anything!" over and over again... which I personally witnessed an actual shoplifter yell while he was being arrested, right after I watched them retrieve the stolen merchandise from down his pants). Giving cops a hard time makes them write little notes in their notebook about how you resisted arrest. If you didn't do anything, resisting arrest is just flat out stupid.

    My guess is that you are not telling the whole truth (or whole story) here. An off-duty cop in the parking lot would have no way of knowing if a store employee told you just to keep walking, unless you didn't just "walk out". Also, most Fred Meyer's stores I've ever seen have two sets of doors at each entrance. The security scanner is on inside, so there are two sets of doors between it and the outside. How did the cop hear the alarm?

    I bet you exited the store while store employees were following you out trying to get you to stop, which they can do in Eugene, among other cities in Oregon. It is also likely your demeanor left much to be desired (given that we are talking about Oregon), and the combination of things gave the officer probable cause. There is no such thing as an off-duty cop when there is reason for him/her to believe a crime is being committed.
