Just a side note. Here in Pittsburgh,the Police Dept announced some changes yesterday in the way undercover cops conduct investigations,largely because of the Kopy's Bar brawl.From now on, when working a case in a bar, cops can have no more than 2 drinks in a 4 hr period,cannot drive afterwards, and are subject to testing for intoxication. There are still multiple lawsuits pending against the cops by the Pa*ans, and none of the cops involved received any real disciplinary action. In fact,believe it or not,one of the cops who was temporarily suspended and then re-instated is actually suing the Club and the bar,citing a lack of security in the bar. This coming from one of four undercover cops in the place. Of course,if the bar did have security,and they attempted to intervene,I'll bet money that the cops would have grabbed them for obstruction. If you haven't seen the surveillance video,just Google Kopy's bar,and include :brawl" or the Club name in the search.
Also using the same search terms you can read accounts of what happened. The Cops really screwed the pooch on this one.
