Just watched a documentary about Colorado allowing pot to be sold publically.
I do have to be careful for NZ don't have two governing houses nor local and central laws, so I don't have a inherent understanding of the USA legal system.
Below ramblings are therefore based on my own random thoughts.
My understanding is that selling pot is against Federal law, but Colorado local law allows it and for the time being the Federal authorities are very closely watching events.
Ultimately, if the Federal authorities don't like what's going on they can step in and shut local legal pot sales down.
It is uncertain which way the Federal authorities will go, so banks won't handle the proceeds from pot sales.
Sales are strong and proceeds can't be banked, so all sales are cash, business owners must handle and sit on large amounts of cash.
Here's my theory.
Pot + cash = Organize crime + guns. Are the local authorizes intentionally trying to put the wind up Colorado citizens and promote an increase is civilian gun sales ?
