If there is something good that came from this, it's the self defense lesson.
One old man with a knife was able to stop 2 younger, larger men, who had him cornered up against a vehicle.
The first man was prison stabbed off him, as the old man ran forward, giving him some space and to nullify the blows coming at him from the rear. Then the old man turns, rear waist locks the second attacker, sticks his knife in, and drags him down.
Violence begets violence. Next time all sides are going to be more prepared. I pray for them.
Here's a video of the fight, although it may have already been posted here, I wanted to post it purely for the self defense lesson.
