Not disputing the above. But keep in mind police officers are hindered by their individual departments policies, procedures, and rules mandated by their mayor and city council. I'm not saying there might not be some fault on the part of some LEOs, but in many cases they cant act (except in reactive situations) unless their superiors grant their approval. This was a possible hostage situation which the departments have STRICK rules which are to be abided by. If an individual LEO decides to go "Cowboy" a.k.a. contrary to the "rules" and something goes wrong they will suffer the consequences. Case in point, there is a story that two different snipers had the shooter in their cross hairs, but were unable to get approval to shoot, by their higher ups in time before the shooter had move out of sight.
