That could explain why the Secret Service was slow to react when told of a suspicious armed character on a roof because he was Chinese. LOL.
The police also had 3 snipers in the same building where the gunman fired from lol.
The director of the Secret Service said the local forces were in the very same building, an account suggesting that the gunman was literally on top of them.
three law enforcement snipers were positioned inside the same complex of buildings
