They are saying that they are not worried about another attack and that people should go about their business tomorrow, but at the same time they are claiming they know nothing at all whatsoever about the shooter. Either they are flat out lying about the safety or their knowledge of motive or they are retarded.
If they truly know nothing at all about the shooter or motive, then any location is a target right now.
This stinks, they are holding back for some unknown reason or are the most incompetent group of people imaginable.
