Another "Church Shooting"
Perpetrators like this one seek places where they think that their potential victims are likely to be passive and unarmed. This perp. was obviously not well versed in cultural readiness. Just as in Texas, I'd say that any person who approaches a contemporary worship service in Tennessee wearing a mask has a finite number of breaths remaining.
Tail wags to the "usher" in this case for taking action.
