>are citizens allowed to voice their frustrations against police officers?

Lol no.

Some states are even making laws against it

Nothing is going to change until a citizen group does something massive.

It must be so cool to be a cop, when you can just literally do whatever the fuck you want.

Wake up, get drunk, try to pull over cars in your personal car, beat the shit out of whoever, kill your neighbor’s dog, start a fight and then kill those people, go home, beat your family, fall asleep drunk.

It’s like the postal game irl.
