Now one fix that removing some of the equipment will do will reduce the amount of psychological impact it has on those wielding it, as in reduce the Rambo effect. The idea of attaching military style equipment to the current problems is only for political purposes, they needed to blame Trump for the violence.
However in the end, there are few alternatives to fixing the police and their application and misapplication of force
1) Restrict conditions that can be placed in union negotiated contracts regarding officer behavior, culpability, and indemnification.
2) If not 1) then make it illegal for the unions to exist with regards to any public servant who is armed
3) civilian oversight boards that are veto proof against the police they monitor. Not only would they review incidents which are questionable they would have to involved in any use of concentrated force to include no knock warrants; something which should be illegal except in the most incredible cases.
4) holding elected and appointed officials of the localities, city, county, or state, accountable for the harm caused by their police forces.
I'm seeing a lot of good, evidence-based reform ideas dismissed as not being enough to "solve" the problem. But reform isn't all or nothing! Where we can make marginal improvements, we should. This is a large, complex, and heavily-entrenched issue. There is no silver bullet. Attack it from every angle available.
