Right, but the posters seemed to (to me) be asking why there aren’t several former cops in jail for long periods, and the answer to that, according to the article, is statute of limitations. Burge is one of the few who faced any penalty, and even in his case, it wasn’t for the crime itself, but for perjury in a civil suit about it, a sentence of 4 1/2 years
At least someone faced some penalty, and it’s great that, despite the statute of limitations, the people prosecuting Burge did what little they could do put somebody in jail for something related to it, rather than the far easier task of just shrugging and sweeping it under the rug, but it’s far short of what should have happened if there were any real justice.
