The fact that we still have gang crime is proof positive that ending prohibition did not end gang crime.
Gangs went into drugs. Again, 70% of crime is drug related, not alcohol related. Look, I don't approve of anyone doing drugs but after 40 years of fighting the supply side of the problem at a cost of billions of $, we have no positive results to show for it. It's time to admit that drug prohibition isn't working and look into trying another approach.
