Zubeidat K. Tsarnaeva, the Boston bombing suspect's mother, thinks this whole thing is a set up.

Business Insider says: Tsarnaeva said that Tamerlan Tsarnaev got involved in "religious politics" five years ago, and that the FBI had previously contacted her about her son's activities.

She says:

"He was controlled by the FBI, like for three, five years," she said. "They knew what my son was doing, they knew what actions and what sites on the Internet he was going [to], they used to come...and talk to me...they were telling me that he was really a serious leader and they were afraid of him."

"How could this happen?...They were controlling every step of him, and they are telling today that this is a terrorist attack," she added.

Further she says:

"FBI, they were scared of my oldest son, they always told me that he's a leader...they are afraid of him because, you know, he is a leader, he talks about Islam a lot."

"They were talking to my son, and they called me officially and they told me that my son is an excellent boy and they have no problem with him," she added. "At the same time, they were telling me that...he is getting information on really extremists...sites, so they were very, very afraid of him. So that's why I think that this is a setup."
