Aggressively violent imagery - equal among both parties?

I must conditionally agree here. In order to continue being the devil’s advocate, does anyone have figures on the number of shootings done in the US so far this month? Anyone have any figures of the number of multiple-victim incidents? And any real reason to categorize this one incident as being quantitatively different than any other shooting so far this year?

I understand the politically sensitive folks see partisan politics (and their personal political bogeymen) in every situation, but as an apolitical mugwump I see another mentally unstable person shooting at a public gathering.
