fired. we don't know how many people might be responsible for those shots, but give us an idea what the reflex is of authorities coming on scene. like james said, they react post columbine, go toward gunfire, but what else? >> we don't know if the active shooter is in the synagogue. this is the busiest time for any synagogue. my father is at synagogue now in connecticut. jews worship during these hours. we may have a situation where there's active shooter that opened fire on hundreds of people. we don't know if he's still in the synagogue, whether there's a hostage situation or ability to get medical care to any casualties mentioned at this point. this is a synagogue, it is in a predominantly jewish neighborhood of pittsburgh and a residential neighborhood. even if the active shooter has left the building, there are civilians surrounding the area that also could be at risk.
