Sad story but I’m sorry, the dad was 100% at fault. He crossed after the arms were lowered, she didn’t have a helmet on, he failed to look both ways or listen, etc. You have to be pretty darn unaware of your surroundings if you can’t see or hear a trolley that’s close enough to hit you and you don’t have enough time to get out of the way. As a parent you are responsible for your young child. Don’t say they are ‘precious’ with your words. You show that they are precious by protecting them. You just don’t take stupid chances like that. Unfortunately he’ll pay for his stupidity with grief for the rest of his life. Fortunately, he has 6 other flushable kids as far as some of these posters are concerned.
