What's your 20/20 hindsight on this?
1: If the victim were able to CC (which he was not at the time).
2: As is (no handgun avail.) No SD training. And some SA (as you will see).
January, 2010, 2:35 AM, -10° (wind chill about -30°)
Victim: 50 YO Male in pretty good shape. Walking home from work (been doing this 1.5 mile walk each way for 15 years). Wearing carhart overalls and a carhart coat. Carrying a lunch bucket. Has a small (2&1/2"-3" folding knife).
Victim: Walking home sees headlights illuminating street in front of him from behind, hears car slowing, sees the headlight beams slow as well.
Victim: Thinks "This isn't good." Gets knife out and opens it with gloved hands, holds knife in front down low while continuing to walk. Turns around.
BG: Within 3 feet (has run up to victim from behind). "Give me your wallet... I've got a knife," shows a long kitchen type butcher knife in hand under coat, to victim.
Victim: "Not giving you anything!" Jinks/feints with right shoulder (like he's going to fight the guy?). Notices BG doesn't even flinch.
BG: Kicks lunch bucket out of victim's hand.
While all this is happening (quickly as you have read this or quicker) BG car is cruising past...
Victim: Is cold cocked from left side and is now on the ground on all fours... still holding his little knife... He is screaming for help, he is trying to get up, he is being kicked, in the head and ribs... BY 4 BADGUYS. He has been stabbed twice in the back with a 5-6" blade that would have gone thru and thru were it not for the carharts.
Samaritan: Heard yelling, turned on porch light, went out and yelled to BGs, "Cops are on the way..! get off him..!" repeatedly... finally, they quit and ran to the car and drove off.
Samaritan: Helped victim up and into house.
Cops called ambulance, victim did not know he had been stabbed. One wound below left rear ribcage, chipped a rib but missed all organs! One wound left buttocks.
What would you have done?
All four of the BGs were caught. One was known to carry a sawed-off shotgun down his pantsleg. All (but one) are free on bond, pending trial... Victim cannot say for certain that it was BG 1 who stabbed him. Victim cannot positively identify any of the other attackers. (fortunately, being dumb criminals, they've been busy rattin' on each other, though "none know who did the stabbing").
