In order to get into the courts in NYC, you must pass through the metal detectors and have your bag searched. They are very strict about that. I was stopped for a while because my hair barrette set off the alarm. I was really surprised to learn that the same security wasn't in place at City Hall. Apparently, security waved the City Council members and the people with them through bypassing the metal detectors. This is how the shooter was able to get the gun in the building. The police officer who shot the gunman was given a commendation from the Mayor today.
This is such a tragedy. I feel so sorry for the Councilman, his family, friends, and collegues.
