This is a pretty sad situation for sure.
Target selection, execution (as in how carried out), killing self afterward, these kind of point to a terrorist to me. Very much like the Pulse attack. I haven't read in the thread yet about perp wearing a bandanna over face like a stage coach gunman. So, maybe antifa? Or one of the "lions" of some terror group?
The young blond witness said he wore a mask that covered the lower half of his face.
That being said, her manner and somewhat conflicting version just seemed off somehow...still trying t o figure out why.
