There has been a string of stabbings in my area over the past few months... All I can think is how bad of an idea it would be for someone to come up to a gun owner with a knife and try to stab them... I'm very resourceful, and I'll be damned if anyone ever attacks me with a knife and wins.
I almost got carjacked once as well... In East San Jose (Very ghetto). It was like 3am and no one was around... these 3 guys start charging at my car from the side walk (both sides)... I was sitting at a timed red light. Fortunate for me I have AWD and about 250ish HP... A nice clutch drop at about 5000rpm = No more mexicans.
