I was coaching a practice, for youth baseball, many years ago. My right fielder pointed out 3 young men, chasing another one, on another field nearby. I started running in that direction. The three caought him and started kicking him. I started yelling as I neared them. They saw me coming and ran away. As they were running away, I noticed all three were bigger than me. The young man had a broken arm. Rescue came and took him away.
I figured three on one was cowardly, so I acted. Now I know, I acted stupidly, and could have been hurt also. I just couldn't stand by, like many others did, and do nothing. I guess, I was lucky, I wasn't hurt.
