Drug dealing isnt a financial crime
It is definitely a very strange one. The classical liberalism argument is that the most prominent aspect remains essentially a financial crime of failure to pay the licensing tax.
That describes a bunch of crimes? If you raid a drug dealer's house and kill a bunch of people in the process, you'll go to jail. If it's the police doing it with a "license" (ie. a warrant), it's suddenly fine. More banal is you driving along, following all applicable laws and causing no issues, but if you're doing it without a license or insurance, it's suddenly illegal.
I pointed it out largely because I find the drug laws to be particularly strange.
