When was the last time you heard of somebody operating an illegal still? Heard of any "alcohol pushers" murdering each other over territory? I've heard of "drug gangs" but haven't heard of "alcohol gangs".
How about shootouts between law enforcement and alcohol smugglers?
Despite the rather considerable taxes on legal alcohol, there is very little gangsterism surrounding illegal alcohol. I look forward to a day when the same can be said of pot. I'll know that day has come when my wife and I can safely travel through the Menocino National Forest and not have to fear running across an illegal pot farm and being shot.
Comparing alcohol and drugs is also naive.
