Marijuana laws: Police spend a year building a case. Judge gives the dealer three months. The dealer serves two then is out. Police officers' time probably in the neighbourhood of $50,000. So for two months in jail, at a cost of about $8,000, trial costs at about $5000, and police time at $50,000, we have enforced a law. Yippee. Real cost of the jail time to taxpayers: $31,500 per month. Nice pay if ya can get it.
