This is what will happen when you defund the police.
Its not the end if law enforcement, it's the end of equal (supposedly) law enforcement.
How is this different than what was already happening other than it's more obvious with a car and app? This has been going on for a really long time in the neighborhood where the mayor of Seattle lives: https://laurelhurstcc.com/security/
So I'm sure this was standard practice in certain areas of LA and elsewhere too.
