If we took a tenth of the money we've handed these armed goons to buy military hardware so that they can prance around American cities looking like the villains in an 80s action movie...
... we could invest it in judges, lawyers, courts, and humane infrastructure. And it would have FAR more real, direct impact on most of the actual problems (and there are many) our system has.
But that wouldn't help anybody bang the racism drum to stay in power. So we don't, and never really have.
