If the round he was hit by was an "FMJ"or full metal jacket, and the shot placement didn't hit any bone, it more than likely passed through so fast and clean as to not cause immediate major trauma. Without having more detail, my uneducated guess would be he simply bled out after that.
Hmmmm It is hard for me to feel to bad about this. These biker gangs are not romantic rebels. Scooter trash like the HA are bad for motorcycling and bad for all those who come into contact with them. However, cold blooded murder, if thats what this was, can not be condoned under any circumstance. Sadly we have a "cut rate HA" where I live which has forced me to arm myself after they threatened to kill me dead for my choice in jackets one day.
Figures a bunch of a$$holes would post on this one. A guy on a bike gets shot and dies (does the patch really matter? Like none of you ever pi$$ed off a guy in a car.), the shooter gets away and you all make light of it. Hope it ain't one of your friends who gets it next! Ever been shot at while riding, I have and to this day have not a clue why. It ain't fun. If it were the Outlaws, there would have been a lot more than just 2 folks hit and he never would have had the chance to pull over. (and if you are wondering, I could give a rats a$$ about the HA/Outlaw thing. That is their problem, not mine.). I kinda hope somone drops a dime on the shooter to the HA's and let them deal with it...would serve the shooter right. If he is smart, and I doubt it, he would be better off turning himself in to the cops, like now. That's my 2 cents worth anyhow. Some of the posters above are beyond pitiful IMHO.
