Good work Dacon. I thought I was the only person who did stuff like that.
As much of a joke as we're making of this incident, it might have been a good thing. If the cops don't include hammers, tools, etc. in their mental list of things that can hurt them, then that might come back to haunt them. So, they see a guy with a knife, they'll take appropriate action. Since they didn't think of a screwdriver or a hammer as a weapon, they might not take the appropriate actions to keep themselves out of harm's way. I once saw a local coroner report that showed the tools typically used in stabbings. Small (less than 2" blade) bladed folding knives and screwdrivers were near the top of the list.
I don't know about you guys, but I'd much rather be shot at with a 22 than have some guy swing a framing hammer at my head.
