Yeah, and real contractors have real places to train, and tend to shoot in a T shirt and nice pants, maybe cargo, may jeans, and talk about working, it being hard, and generally give you the impression they are something like middle management at a large but un-named corporation, but they like to practice with their guns to blow off a little steam.
Or they just kinda pass themselves off as LEO or military but never say anything out right.
Mall ninja, unlike an actual ninja, do their best to be seen and noticed, often only dangerous to themselves, except for the incidental danger to bystanders due to thier stupidity.
BTW, I have been trained by, worked with and had a few friends ship to Iraq as contract security. You would be more likely to encounter them getting sorority girls drunk than at a range, especially if it is during the morning on a weekend, they are still passed out.
