I think we're seeing exactly what everyone is protesting about
To be fair, I think we're also seeing why cops are so twitchy. How many incidents of shootings, stabbings, molotov cocktails, bricks, water bottles, etc occurred this week with an LEO as the target?
Like the poor NYPD footman who got blasted on social media and by his governor/mayor for pulling his weapon -- and then the longer clip came out that showed he'd been tackled and people had taken turns throwing things at his head first, and when he finally got on his feet, he pulled his weapon. Then last night a guy slashes one officer in the neck, takes his weapon and shoots two other officers...
I also think we've raised a generation with increasing numbers of self-absorbed douchebags who make up the population (and police). It's not really surprising that there's more conflict between them.
There are some relativity easy uncontroversial steps stopped primarily by budget concerns, imo.
First, it's impossible to effectively police a community without the involvement with/in the community. Having enough officers allows smaller beats (along with faster response time. That means people are seeing the same cops more frequently, and they have time to do more outside of actively responding to calls. Getting involved in the community and having interaction outside of official meetings. Humanize the neighborhoods and the officers. Make them get out and learn people's names, hear their concerns, build some trust. A community meeting is great, and a formal setting is probably fine for some things, but how many people are interested and attending?
Training, training, training. Also, experience, which means hiring/paying experienced officers instead of hiring new cadets and candidates.
There is zero excuse for any department in this day and age to not have body-cams and dash-cams. For everyone's protection. That's relatively small money, which should obviously pay dividends.
A deliberate shift towards increasingly deciding to charge officers who sit quietly on offenses instead of turning in other officers. LEO (and politicians and other state agents) should face harsher penalties than the citizenry for violating the social contract which gives them the authority they hold.
