Communication Breakdown

I was out shopping yesterday when I heard about the shooting at City Hall. When I got to the bar around 4:30, they had it on TV. The story I was hearing was that someone let off 20 rounds, the guy who did it got away, and that it was considered to be random. How the hell does that story jibe with the actual story? If the whole thing went down at ten after two, how could they not know by 4:30 what had actually happened? Way to go, local news. And if this was a story fed to them by City Hall, what was the point? Were they embarrassed that Councilman Davis signed his own death warrant by skirting metal detectors with some apparent weirdo he'd just met two weeks ago? Did they want to wait to reveal that a police officer had done his job because theycan never be sure if NYPD officers are playing with a full deck?
