The meth heads that buy the guns and meth only rob and kill each other.
The Hell's Angels only drive on "special" streets and never ever encounter civilians. They only drink at special "biker" bars and only eat at special "biker" restaurants. They only shop at special "biker" liquor stores and live in special "biker" communities.
meth effects society at large are you so dense that I really need to go and get the evidence about the effects of the meth trade has on society as a whole?
Now back up your statement that the average person isn't effected by meth and arms peddling bikers.
So yes it is implied that your so fucking daft as to think that the actions of the Hell's Angel doesn't effect society at large.
