a neighbor was telling me a story the other day.
he was stopped in traffic and had his window down(no a/c) when some guy came up out of nowhere and bashed him in the face 3 times real fast, and ran away.
since then he carries a 8" filet knife in his car door(not alowed to own guns).
There is only one tactical principle which is not subject to change. It is to use the means at hand to inflict the maximum amount of wound, death, and destruction on the enemy in the minimum amount of time."
