But the state of the police and its militarization is due to policies of the last decade, meaning that deescalation wasn't tried at all. The former terrorism has become domestic terrorism, something early critics predicted (wasn't even hard). The loudest voices we hear from seem to not be able to hold a thought, because the other side needs to be silenced first.
Ultimately I believe many cops will quit due to lacking support of their governors or president. But I doubt we will see significant changes. Private security will become an even more booming market. Police departments will lack funding but will be sold expensive riot gear.
