Last night Twitter and Facebook came alive about a shooter in downtown Dallas, We turned on the local news to see excellent coverage of the horrific sniper attack upon police. We live 25 miles north of downtown Dallas, We know downtown well. I worked downtown as a young man. I still go to court there. We ride the train in some Saturdays to the museums or events. So all these city street blocks in the news are spaces we pass through. This horrible terror event is so sad.
