Yesterday, before I left the dialysis center, I had chat with my black friend, a dialysis patient, on next chair to my left. I made a quick reference to GZvz TM case and I was joking, I was wearing a red sports hoodie (in support of Mr. Marting?) AND I do carry my gun too. The gentleman went on to describe the injustice suffered by the black people for ages in US till the days of the civil liberty. It was a very interesting talk.
