Very sad story. In this day and time, if you are going to escort someone in that situation, be prepared for the crazies. People that cause others to be concerned for their safety, without reason, are inherently unstable.
This is another reason that I condone carrying a concealed weapon. I may NEVER have to use it, but there may be just one time when I do. And it may save a life. Now we have a good man dead and a family in tatters because a slimy assed individual thought he had the right to terrorize a woman. Sad indeed.
