“Maybe some online chatter, maybe some online activity that may have been worrisome to federal law enforcement, but no plot coming out of these young men, these teenage boys out of Dearborn,” said Amir Makled, who says he represents one of those arrested.

The attack was a targeted act of violence, "believed to be motivated by the assailant’s anti-religious beliefs against the Mormon religious community," the FBI said Friday.

The former Marine who opened fire in a Michigan church and set it ablaze in September was motivated by “anti-religious beliefs” against The Church of Jesus Christ of Latter-day Saints, the FBI confirmed Friday.
