With respect to the first point, concern about the G20-related emasculation of the Citizen Police Review Board is warranted -- but tempered by the fact that Vic Walczak and other lawyers for those abused during the G20 event have assembled another review board, this one comprising the judges of the United States District Court for the Western District of Pennsylvania.
With respect to the second and third points, the analysis seems cogent.
With respect to the fourth point, the Cometeer's continuing objections to dismissal of the The Not-So-Great InsolvenCity Parking Garage Sale evokes a fine exchange from My Cousin Vinny:
Judge Chamberlain Holler: Mr. Gambini?
Vincent Gambini: Yes, sir?
Judge: That is a lucid, intelligent, well-thought out objection.
Gambini: Thank you, your honor.
