Another tragedy rocked the United States.

The event celebrating the 117th annual race this year was held in memory of the children and teachers killed in the Sandy Hook shooting in December. One bomb went off, followed by another as 26,000 people were participating in the race and around 500,000 spectators watched the event nearby.

Patton Oswalt wrote a longer note on Facebook, "Boston. F**king horrible. I remember, when 9/11 went down, my reaction was, 'Well, I've had it with humanity.' But I was wrong. ... I don't know what's going to be revealed to be behind all of this mayhem. One human insect or a poisonous mass of broken sociopaths."
"But here's what I DO know. If it's one person or a HUNDRED people, that number is not even a fraction of a fraction of a fraction of a percent of the population on this planet," he added. "So when you spot violence, or bigotry, or intolerance or fear or just garden-variety misogyny, hatred or ignorance, just look it in the eye and think, 'The good outnumber you, and we always will.' "
William Shatner also condemned the incident, "Thoughts going out to the people of Boston. I hope whomever did this is brought to justice."
"Survivor" winner Ethan Zohn who was participating in the marathon tweeted, "I'm OK. Most importantly, praying for those injured and affected by this. Still don't have a lot of info. Thanks for your love and concern."
New Kids On The Block's Joey McIntyre was in the race as well. He he was "running for my mom's memory," revealing that she suffers from Alzheimer's. "There was an explosion by the finish line about 5 minutes after I finished," he wrote. "I'm ok but I'm sure there are many hurt."
Donnie Wahlberg responded, "Just heard that @joeymcintyre is ok! Thanks to everyone for tweeting! Scared for everyone else in Boston. #PrayerForBoston please."
President Obama said, "We still do not know who did this or why," warning people should not "jump to conclusions." He vowed, "We will find out who did this, and we will hold them accountable," adding, "Boston is a tough and resilient town, [and] so are its people" and "the American people will say a prayer for Boston tonight."
