however the spearies possibly acted (probably panic for a start), y would you leave the guy there. get him in the faster boat and get motoring , report the destination on the way. if i had the faster boat there would be no question of getting him as close as possible to medical help, even if it was only a few minutes less, it could be the vital few minutes the poor guy needs to survive before bleeding out or dying from shock.
and yes im guilty of the knee jerk reaction to hearing only partial facts, but still its potentially someone's life were talking about here, act fast and act now.
