The National Firearms Act of 1934 was actually a direct response to the acute rise in prohibition (1919-33) engendered gun violence.
PROHIBITION EQUATES TO MORE VIOLENT CRIME WHICH LEADS TO MORE CALLS FOR GUN CONTROL
The University of British Columbia, Vancouver, Canada recently reviewed 15 studies that evaluated the association between violence and drug law enforcement. "Our ﬁndings suggest that increasing drug law enforcement is unlikely to reduce drug market violence. Instead, the existing evidence base suggests that gun violence and high homicide rates may be an inevitable consequence of drug prohibition and that disrupting drug markets can paradoxically increase violence."
Prohibition has diverted police resources away from other law enforcement activities, with the result that violent crimes and crimes against property have been higher than they would otherwise have been. To the extent that communities divert law enforcement resources from violent crimes to illegal drug offenses, the risk of punishment for engaging in violent crimes is reduced.
During alcohol prohibition, all profits went to enrich criminals and corrupt politicians. Young men died every day on inner-city streets while battling over turf. A fortune was wasted on enforcement that could have gone on education, etc. On top of the budget-busting prosecution and incarceration costs, billions in taxes were lost. Finally; the economy collapsed! Sound familiar?
Prohibitionists, and their gun-control criminal friends who live in a crack-house called Congress, are having a ball and it's all on our tab.
