> if someone smashes into my parked car and flees, most major cities won’t investigate

I've had three home break in and robberies. In no case would the police even show up to take a report. In the case where my cameras identified the perps and I tracked down and documented them trying to fence my property, and worked with other neighbors to document an actual crime syndicate that was taking orders for specific things to steal, the police would do absolutely nothing. Police are about collecting fees from "in" drug dealers in return for looking the other way, while protecting their turf against incursion from rival drug gangs. They are also involved, along with judges in the USA, with child sex trafficking. The idea we need to give up freedom and be surveilled by these people is unrealistic.
