The mafia really became hugely powerful in the 1950s controlling large cities in America. The Kennedies fought them and it cost them their lives. The US is riddled with more minor criminals these days as proved by the 2.3 million in prison currently. If each prisoner costs the taxpayers about $100,000 a year plus the costs of an army of law enforcement then that's a lot of money. Way up in the trillions without a single useful return.
2,300,000 * 100,000 + law enforcement = $230,000,000,000 plus ??????????????????
Putin would probably cull 10% a year. The figures would drop substantially.
The decent folk of the US could live again without fear. It could come down to letting them go or culling the worst offenders.
