Sad situation. I read through this story and saw a number of witnesses who watched as this guy dragged this woman through the hallways, at one point down an escalator it appears, and then shot her point blank while people sat and watched. These "witnesses" should be absolutely ashamed of themselves for letting this woman die. I am absolutely digusted by the display of cowardness that a number of these individuals showed.
Things like this help solidify one of the big reasons I carry to protect myself and my family. It's more and more obvious that there certainyl won't be anyone else out there who'll step up to help out. Don't count on your fellow human beings to come to your aid!
