Yes you can arrest a police officer. . But they have to be using excessive force or seriously abusing his/her power. If you have to call 911 and ask them to bring a Supervisor down and then ask them to bring a different agency to the scene. You should have another jurisdiction file the report. Once a different agency is involved they cant cover it up that easy. Make sure you have a copy of the reports, and above all else don't give up any evidence like the tape or chip. If you can upload it to a website do that. Make a copy of it. . A police officer is not above any law. They may think that they are. They have higher standards then a citizens. In Some states (like Florida) Local , County, and state police actually ticket, arrest and file complaints on each other. So don't think cops get away with it. .
