The only time I was scared was a drive by when a Mac-10 was emptied at me because it was just so random and without warning, and those things just keep on going buddabuddabudda for ages, it's not like a pistol where there's a few shots and it's all over, the shooting keeps on coming with a submachine gun and that gives enough time for the fear and adrenaline to get really quite high. It's the only time I can think of when I didn't confront my assailant, I just got the hell out of dodge.
Oddly it never really sank in and once away from it I just carried on as normal, I said to my brother who I was on the way to visit at the time "I just got shot at by a Mac 10", he didn't believe me because I was just so calm about it. It was only in the light of day when my car had some dents (I assume from ricochet as a direct hit would have penetrated) that it really sank in, and by then it was too late to be bothered by the whole thing so I just shrugged it off, the car wasnt great anyway, I was still alive, so it was all a bit 'whatever' really.
What the intended use of weapons is, is beside the point. The gun-control debate is about the consequences when a weapon is NOT used as intended: when the owner loses his cool, goes completely crazy, or when the weapon falls into someone else's hands.
Thats the scariest thing with nailguns, as long as the tip of the nailgun is pushed down onto a hard surface, ie wood, or in this horrible case someones head, it will fire.
Pushing down the tip pushes the safety clip back allowing it to fire.
Hell, you dont even need to push down, the safety can be pulled back using just your fingers and then it can be fired at whatever you want to fire at, which is a stupid and dangerous thing to do, but also shows the power of these things, as i saw someone do this on site one quiet day and a nail could be fired at least 50-60 metres .
Most nail guns have such a simple safety that it can be overcome with a simple strip of duct tape.
There is the odd one that has a double interlock that actualy forces you to remove the gun from the surface and place it back again to fire the next shot though. but I got bored one day actualy rigged a paperclip to make that work on a trigger pull.
Weapons of any type shoulden't be banned in my opinion, and I definately doubt that it will even come in to question with nail guns. People just need to become more responsible with things. A gun and a car are both just as deadly in the wrong hands.
If anyone pulled a weapon on me I realy hope for thier health that they intend to use it, because if they don't they arn't going to have it for very long.
