Yours is a straw man argument.
Bootleggers moved on. To drugs, gambling, prostitution and worse. If you don’t hear or see the violence, then pull your head out.
While I do not personally see Mexican drug gang-related violence where I live, I absolutely recognize that it exists and deplore it.
I agree that criminals have ditched bootlegging in favor of more profitable activities. You should ask yourself: what do these activities all have in common that makes them so lucrative?
