Well, MyOpinion, two things are needed, intent and the necessary means to carry out that intent and maximize the results. At least one shooter was identified in initial accounts as having an AR15. We will see what an official investigation finds. There is tremendous racial anger right now on all sides, not that it justifies premeditated murder. Healing is needed right now, but certain brazen political forces will likely now throw more fuel on the fire for calculated political reasons, creating even more anger. That anger is well shown by the many blatantly racist posts to this tragic story.
