There was an excellent article by a black, ex prosecutor, now at GTU. He chose law to change it, sorta like I suggested above, but found that in reality he was so dependent on cops to do his job that it corrupted him. He opines that all cop shootings should go to a different jurisdiction as it is in the best interest of the prosecutor to lead the Grand Jury to never press charges against the cops. So maybe that would be a good start.

I believe it was a NYT article.
