We should all try to be good Samaritans but at the same time we must remember that sometimes a situation is not as it appears.
There was a tragic incident several years ago in Fort Worth, Texas where an individual with a CCL, and carrying, witnessed what appeared to be two men in ski masks beating a teenager in front of a Target store. As they tried to drag the boy into a van, the CCL pulls on the two in masks. They run to their van. The CCL shots and hits one perp. The other perp speeds away.
As it turned out, the boys were local high school students shooting a make believe "kidnapping video" for YouTube. Who's at fault, good Samarita, high school boys? Doesn't matter, innocent lives were destroyed all around.
Please think before you react with force to any situation.
