re: If Alcohol was illegal would there be less wrecks

Short answer is yes.

Long answer is yes... but....

When we had Prohibition consumption decreased dramatically that first year. Within a year or two it was back to around 70% or so of what it had been before Prohibition.

If you make booze illegal it will take about a year for criminals to really get their alcohol smuggling operations going and then its going to be everywhere. If you think South American drug cartels are a pain now, wait until they get into providing booze.

The Mafia was strictly small potatoes before Prohibition after all.

The other problem is that are probably millions, tens of millions actually, of functional alcoholics in America. If you cut off their supply of joy juice they are going to swamp our health care system to such a degree it would make the Opiate crisis look a slow day at a rural health clinic.

I am here to tell you, those people will buy their booze even if it is illegal. I hope you have a lot of jail cells to put them all in.

Long term the solution is education about the dangers of driving while drunk and spending more money on addiction therapy.
