It is indeed how you say it.
Further, it appears that police love prohibition crimes.
Pot smokers are easy to bust. They rarely, if ever, put up a fight.

Look at the statistics of who is in prison.
Violent criminals - tiny percentage, only caught when they didn't leave the scene fast enough
Actual thieves - larger percentage, usually caught with possession, or ratted out by their friends
Drug offenders - largest percentage

The police almost never investigate a burglary. They show up to give you a report number. The police don't even investigate murders more than half the time.

Its a racket. And not what we (think we) pay police for.
