I have been working security out at the local halloween haunted house - "Trail of Terror" in Shakopee, Minnesota. When we are escorting naughty-doers around site one of us walks in front, one of us walks behind to keep an eye on the people we are escorting.
We had some problems with a guy who was underaged, and drinking and trying to sneak onto the grounds without paying. Normally we would have called his parents and had them pick him up, but he was with freinds and they were going to watch him. Well his freinds bought tickets and went inside, he kept trying to sneak in. We pulled beer off of him and he informed us his freinds also had beer on them, a double whammy in our book for bringing liquor onto the premises, but also all being underaged. We went to get his freinds and found them across site, and as per usual operating procedure, walked them to the front gate, me in back.
We are walking two guys, they are walking on in front and to the left, the guy in back is to the right almost dirctly in front of me. We have a fireman walking to the left of them (The fire crew helps us out since all of them are atleast 6'1" 250 lbs or so) the security guy in the front and I am in th back following at about 10 feet.
The guy in back reaches into his pocket. Typically those who are drunk tend to want to smoke as well and so they often go for cigarettes or whatever, and we don't sweat it too much. I was watching him and saw him start to remove something from his jacket pocket which at first appeared to be a beer can. He got it free of his jacket and it turned out to be a black pistol of some sort, it appeared to me to be a glock.
I hit him from behind at full tilt, sort of picking him up and slamming him to the ground. The gun flew from his hand immediately. I slammed him to the ground then pinned his arms behind him and we cuffed him while the fire guy held onto his buddy.
We found out later it was a pellet gun and he claims he was trying to dump it in case we called the cops. He says he didn't know I was behind him.
