The shooters were revolutionary leftists of the OWS sort. Without exception, all of the wanton murder sprees and assassinations (or attempted asssination) of the last 150 years has been done by a DemonRAT: Lee Harvey Oswald, James Earl Ray, Sirhan Sirhan, John Hinckley, Lynette "Squeaky" Fromme, Nidal Hasan, Eric Harris and Dylan Klebold. The list of murderous leftists fills a book. In America's history, there has not been a single true Conservative engaged in such violence. Why? It's an established fact that Conservatives value life but liberals do not.
What IS your point? All massacres are caused by Democrats or ....What?
