Patriot Day Boston Marathon Massacre

What an odd day to blow up a marathon -

Multiple casualties are reported after at least two explosions rocked the area near the finish line of the Boston Marathon.

Competitors and race organizers were crying as they fled the bloody chaos, while some witnesses reported seeing victims with lost limbs.

"Somebody's leg flew by my head," a spectator, who gave his name as John Ross, told the Boston Herald. “I gave my belt to stop the blood.”

Witnesses heard booms that sounded like two claps of thunder near the finish line inside the Fairmount Copley Plaza Hotel, according to multiple local reports.

This would have had to have been a huge bomb to be amputating limbs from a distance here. And not just one, but two? Plus, there's the timing of the holiday which lines up with the 'let's blame the founders' mindset -

This is Patriot’s Day, which commemorates the battles of Lexington and Concord, fought near Boston in 1775. Patriot’s Day is annually held on the third Monday of April.

Is a message being sent to "Patriots" worldwide? Will the culprit be someone who 'feels we need a new civil war'? Once again, we need more details before we can form substantive opinions.

Update:
A reported third bomb is detonated by police.

Update 2:
12 dead, 50 injured. (Waiting for that magic #13) Is it possible that Newtown victims were there?

Relatives of the victims of December’s school massacred in Newtown, Conn. were among those attending the race finish at a VIP area. It was not known of any of the relatives were among the casualties. 

Update 3:
Note the "international theme" to the area that was targeted. Don't be surprised if lines like 'This was an attack on the international community" start flying around.








Update 4:
A suspect is being guarded -

Authorities have a identified a suspect, who is currently being guarded in a Boston hospital with shrapnel wounds.

A fourth bomb is reported -

According to reports, authorities in Boston found two more explosive devices that had not gone off and police were dismantling them. The airspace above the city was ordered cleared as well.

A third explosion is linked by police to the other two -

Police confirmed a third explosion at JFK Library in Boston. It was unclear if the explosion was linked to the two earlier ones that took place at the Marathon.

Update 5: 
The suspect is a Saudi national.
