Because it might stop a murder. This video is pretty graphic, not for the faint of heart.
Video takes 11 seconds to get started, be patient.
Here an elderly man saved the life of a woman who was being repeatedly stabbed by her estranged ex-husband. This is caught on in store security cameras. One thing that is pretty amazing is that the camera system is tracking the man who did the stabbing yet store security did not show up on the scene until after the elderly man stepped up and killed the attacker and then after another customer came up to help the victim.
You’d sort of think that if the security cameras were tracking the bad guy they would have had a security officer on the scene much quicker?
