If that’s the case, I give the guy a very small amount credit for warning of the bomb, that could have taken out a lot of innocent people.
Christmas can be a hard time for many, this year more so. He/she would have had time to change their mind during the countdown without anyone coming in, plus give people a chance to flee. Going out in a dramatic fashion is what some choose to do. 8 years ago on Christmas Eve in Webster NY a guy set fire to his house and waited for the first responders to arrive, he killed two firefighters and wounded three others before killing himself.
I hope the remains are the bombers and not someone else’s.
We should all try to appreciate every day, even if things are sometimes bad. We only get one chance at this and who knows which day is our last.
