So...if the victim's friend is telling the truth here, it's a very ugly example of the costs of all that hate directed towards homosexuals.
Guy has a heart attack. Friend of guy begins CPR. Police chief tells guy to stop CPR. Says heart attack victim was HIV Positive. Victim is gay, but not HIV positive. Police Chief tells same thing to folks in ambulance. Victim winds up dying.
(If you do CPR right, there's no chance of HIV transmission through it, btw, even if the guy was HIV positive, which he was not)
