Oh indeed we have. We've asked each other, what if... (brother's name) was the one on the train threatening to kill people, demanding food, money, and all the other ranting and raving he was doing... and ran into Daniel Penny that day. Without exception, all agree they'd still support what DP tried to do to protect innocent people on that train car, knowing full well he never intended to kill the man, but simply restrain him until police arrived. The end result was a tragic accident, not a crime.
The fact that DP didn't release his hold on him, nothwithstanding. There's no way he could have known that if he released his hold, JN wouldn't jump right up as soon as he was able, and make good on his threats. While DP didn't know JN's violent criminal past, he didn't need to. He heard him first hand threaten to kill people. If my son or brother or any other family member did that, I'd hope to God someone would have the courage to step up, intervene and stop him before he actually did it.
