i think the other occurrences around this date are just coincidence. i'd imagine you can find tragedy in any week of the year.
my thoughts were that either it's anti-government americans who did this, to coincide with patriot's day.
or it just happened to be patriot's day, and they focused on a big crowd being around for the marathon, which just happens to be held on the holiday commemorating lexington and concord.

just read that there were just the two bombs, that reports of unexploded devices isn't true. the bombs contained bb's and ball bearings, to cause as much injury as possible. at least 2 dozen people suffered amputations from the shrapnel. others may lose limbs due to the severity of their injuries. it's horrible.
a 20 year old saudi man is being questioned, a rental van is being sought, and an apartment was searched, with bags of evidence being removed.
i hope they find the bomber(s) quickly. i think if it were a terrorist group, they'd have claimed responsibility by now, but no one has.
