I don't care where in the world you live, if you haven't seen what happened yesterday at the Boston Marathon, you must be living under a rock. I've been following it as much as possible on the news, and it's incredibly tragic. That someone would do such a vile thing during an event that is supposed to bring people from all over the world together makes me disgusted, angry, and saddened.
We do mass casualty drills several times a year, but I haven't actually had to deal with one myself. Having watched some of the news reports carefully, it looks like the first responders (police, fire and rescue) did a fantastic job managing the situation. Triaging scores of patients at one time is a nightmarish proposition - sometimes you have to make the decision to pass over someone who is gravely injured (but still barely alive) in order to try to save others who have a better chance at surviving their wounds.
My thoughts are with the injured and their families. I hope the perpetrators of this heinous crime are found quickly and brought to justice even more quickly.
