Thank you for the clarification. If you would have asked me before tonight, I would have said this wouldn’t happen in Texas, let alone Dallas. So, I cannot answer your question. If you find out, let me know. I just cannot wrap my mind around it.
As a kid, I watched something similar unfold in New Orleans (January 1973). Many years later, I worked downtown, a half-block from the hotel where that sniper had shot policemen (and ended up cut down on the roof of the building, by machine-gun fire). I could never walk past that building without thinking about that day.
It can happen anywhere.
