WHY!!!!!!
I see again you have invented a reality which did not exist yet. High powered sniper rifles and uzzis in 1945 chicago? Uzzis were just being made in the 50s be the israiles during there war for independence. Highpowered rifles like the one you showed weren't around into 70s. Though sniper rifles have been around along time just not like that. At least try to be realistic in these. ASS. And by the way the mafia would not touch drugs back in the 40s.
