Questions are being raised after a man with ties to the Bay Area was shot and killed by police in Boston on Tuesday.
Officials say the suspect was being followed by the Joint Terrorism Task Force and was wielding a military-style knife at officers.
Officials told NBC News the officer and agent had been investigating whether the man, identified as Usaama Rahim, had become radicalized by ISIS-inspired social media messages.
The FBI and Boston police say they foiled a suspected terrorist plot to kill police officers, but some, including Ibrahim Rahim, think the cops pulled the trigger too soon.
Rahim is considered a moderate and spoke out publically against the Tsarnayev brothers role in the Boston marathon bombing.
