Because of the bootlicking statement you made.

Cops in America are not your friend. They have no duty protect nor serve the American people. Their job is to write tickets and make arrests, to help fuel the for-profit prison system and keep the money flowing. (Empty prisons don't generate profit.)

Their second duty is to constantly harass people of color to make them feel unwelcome in the country. It starts with approaching brown people who have committed no crime and asking for ID. The goal is to be escalate things in hopes that the person they're harassing will fight back, that way they have an excuse to charge them with assaulting an officer or interfering with police duties.

It's sick, twisted, and fucked up, and the worst part about is is that over a 3rd of the United States voting population supports this behavior.
