One of the Chechen terrorists who carried out the Boston Marathon bombings could have been deported years ago after a criminal arrest and/or conviction and the other was granted American citizenship on the 11th anniversary of the worst terrorist attack on U.S. soil.

Tamerlan Tsarnaev, the 26-year-old killed in a wild shootout with police, was a legal U.S. resident who nevertheless could have been removed from the country after a 2009 domestic violence arrest and conviction, according to a Judicial Watch source. That means the Obama administration missed an opportunity to deport Tsarnaev but evidently didn’t feel he represented a big enough threat.

The 19-year-old, who is still on the run, was granted asylum in Arlington Virginia on September 27, 2002...

"I don't argue with fools who say Islam is terrorism it's not worth a thing, let an idiot remain an idiot," he wrote in January 2013.

Also, the mother could have been deported for shoplifting. I don’t know if she was involved with one of those shoplifting rings = who often resort to violence - or acted by herself.
