Who takes that seriously? I'd like to take a look at the last two "don't wanna post this on the internet openly" things I remember:
#1: The concept of using the "Machine Gun" in .50 BMG as a way to ban the round.
#2: The idea that burglars actually use
metal detectors.
I'm sure you people can name a bunch more. One of them I remember from Warriortalk
was a technique of using a flashlight to disorient people, which the poster insisted should only be taught to certified LEOs.
I can understand #1 as a "I don't want to post this openly (because people will laugh at me)", but #2?! Not all criminals are plumb stupid, much as most of the membership would like to believe.
If I were going to do some burglary, a metal detector to run along walls and floors would be high on the list- one of the really neat little ones from Edmund Scientific. Looks like a tiny radio. So would be inexpensive NVGs with an infra illuminator flashlight, a compact infrared remote thermometer, pair of in-the-ear hearing enhancers, OC spray or stungun for unexpected dogs, etc. Not to mention a cordless drill, glasscutter, and whatnot. OH NOES, I just may have given a potential burglar a list of useful tools! I better edit it out and say how I "shouldn't talk about that sort of thing openly".
Point being, if someone is on the internet to the point of browsing a forum you use, and interested in doing something wrong, they've probably thought up, researched, and decided apon the tactic or item that you think is some kind of big secret. Geez.
So why do people do it? To impress people? To feel superior? To deprive decent people of knowledge that might be useful, on the tiny chance that someone is going to use that information for malicious purposes, but would not have known about it otherwise?
