It is simple to understand that that is the rule. Its also very simple to understand how absolutely fucked up that is.
Next time they shoot another innocent person and murder them at the wrong address is the person who's address they were supposed to be at going to be held responsible?
To add to this, say an addict buys drugs from a dude but that dude is a cartel member and murders a family after a few months. Addict didn't give him the gun, maybe addict didn't even know he was cartel but because of ol' Rico since you interacted with a criminal organization your hands have blood on them too?
Lets say I along with a number of others bought drugs from a dude who used that money to buy more drugs to sell and some of those drugs killed someone.
Is everyone that bought from them responsible?
