Note no loud calls for gun control when a black is pulling the trigger.
Liberals have no principles, just agendas.
Democrats have always been about getting the most votes by whatever is the cheapest, fastest method possible.
They've been like that since slavery. Which they supported.
I think they're waiting for a few more incidents, enough to get people REALLY scared… possibly even trying to instigate stuff at the conventions so that it serves the dual purpose of disrupting political processes as well as fomenting terror. They tried to do it w/ Sandy Hook, and with the Orlando shooting, but were rebuffed, so I think they're going to "make it real" to everyone in order to try passing it.
