I could get the jump on four people with a pocket knife and maybe kill them all, the tool makes no difference, so right away this guy is full of crap. If our gun laws made sense and people were allowed to defend themselves in public, someone else who didn't get suckerpunched along with those unfortunent police officers could have helped them. Our problems with violence have nothing to do with tools and everything to do with our sick, disgusting, perverse, free love lawyers and social 'do-gooders' letting these scum bags out of prison and into the public, and then disarming the rest of us as if the police could be our shadow all the time.
