This line of thinking is actually pretty lazy. It's straight out of the 90s. We've been "reforming" since Rodney King got the shit beat out of him on TV.

We don't have anything resembling the sort of constabulary we need. We have impulsive children running around with broad authority and no oversight, slaughtering and brutalizing people in the streets (and with dubious impact on public safety at that). That's urgent. That's grounds for pulling the plug. If a broken pipe is flooding your basement, you don't give the waters the "proverbial pat on the head." You don't go "well I need water, I can't just turn it off!" You stop the fucking flooding, and then you figure out how you're going to take a shower.

"Let's tweak this shit for another century until we get it right" is just lazy as hell. It really diminishes the severity of what we're facing: the state is routinely killing, brutalizing and violating citizens' rights. That's fucked.
