Nope. My father-in-law met the Tsarnaev brothers. They were out shopping for electric switches. My father-in-law worked in an electric supply store that didn't stock the right type of switch, so he directed them to a store that would have the needed part. He later recognized them, leading to the store video being seized as evidence and helping to track them down. Feeling of guilt over helping the Tsarnaev brothers gnawed at him, worsening the bad lifestyle choices that led to his death before he could testify. I don't think they'd go shopping for a switch if they didn't intend to build the device. There might have been a local co-conspirator such as Tamerlan Tsarnaev's wife. Wikipedia says: Her web history included searches for "If your husband becomes a shahid, what are the rewards for you?" and "the rewards for the wife of Mujahedeen."
