So this happened right in front of me.
SS, I'm sorry you had to go through this. It will always be with you. But for the sake of the victim I'm glad you were there. Way to step up to the plate!!! As much as this will always haunt you a bit, you can always be proud of how you handled yourself when the time came for action. You helped to save a man's life. It doesn't get much better than that.
