couple that with the following issues.
1) IF you try to record the incident, your camera will be confiscated and video will be erased or the camera turn up missing.
guy records cops, gets arrested, camera and video are missing
If you DON'T record the incident, the court will give greater weight to the cops testimony than yours.
2)If your video survives and can be brought forward, the prosecutor will most likely drop charges, but this is after your cost of hiring a lawyer to defend you against the charges as well as whatever you had to post for bail. If you didn't lose your job because you got arrested, you're lucky.
3) the prosecutor will either decide not to press charges against the cops because he works with them daily, or just not to alienate the entire force. A grand jury is made up of morons, usually, and will choose to not indict an officer because too many people in this country are raised with the belief that cops are good guys.
4) without hard evidence like video, most lawyers will not take up your case against cops. SOME will take the case because they know they can get a settlement from the city, of which they will get 75% or more and you'll get the measly rest. Last case I read about unlawful entry settlement was 25k, lawyer got 23k of it.
5) prosecutors are interested in conviction rates to further their career. they have absolute immunity from wrongdoing, so there is nothing to give incentive for them to act ethically.
7) this is just one more right eliminated. how many more will the courts try to get away with eliminating?
