"Yes, sir."

"Close your phone."
"No, sir."
"I'll light you up." <Commences beating>
In the 1960s, a solution was for citizens to carry firearms for defense against the police, and it worked, at least a bit.
Until of course they passed laws prohibiting that.
Don't rely on your phone if you think you're at risk from corrupt policing.
If I had my way, all government bureaucrats would have a body cam glued to their chest, not just law enforcement. Humans are prone to bad behavior if they think they can get away with it.
And do carry a gun. And have a shotgun for home defense. And a long gun for when it's time to water the tree of liberty.
I don't personally think we're their yet because excessive police violence in my mind is simply a result of having a large amount of society that thinks you can pick and choose which human rights apply to whom and when and I think police violence will go away as that gets solved.
