ISIS Comes To Warwick (UPDATED)

Today the quiet neighborhood of Governor Francis Farms became the center of a federal-level investigation as state and local police, as well as members of the FBI, investigated a house on Aspinet Drive linked to Usaama Rahim, a African American Muslim killed yesterday in the Roslindale neighborhood of Boston by police.  Rahim, whose older brother Ibrahim is an imam at the Oakland, California Lighthouse Mosque and earlier Masjid Al-Quran in Dorcester, was said by police to be carrying a "military-style" knife.  However, the brother of the deceased claims that his brother was on the telephone with his father at the time he was confronted at a bus stop beside a CVS Pharmacy, hoping to create a record.  The authorities claim that the deceased had recently become radicalized by ISIS via the internet and had been under surveillance for some time.
Police Commissioner William Evans later convened a meeting with local civic religious leaders, including Boston Imam Abdullah Farooq, and screened a copy of the security camera video.  Farooq said that he felt the video was inconclusive and described it as vague while also saying that the deceased was not at a bus stop, was not shot in the back, and he appeared to be approaching the police officers.
This is not the first brush with violence linked to Islam for Rhode Island.  It is known now that a man from West Warwick was perhaps involved in radicalizing Tamerlan Tsarnaev, the elder brother of convicted Boston Marathon bomber Dzhokhar Tsarnaev, who was killed in the manhunt for the two assailants after the 2013 attacks.  The elder Tsarnaev also was married to a woman originally from North Kingston.  However, the wind blows both ways on this account.  On September 12, 2001, Providence Police responded to a tip and arrested Milford, Massachusetts resident Sher J.B. Singh at the Amtrak station over alleged connections to terrorism, even though Mr. Singh was in fact a Sikh, not a Muslim.
UPDATE, JUNE 3, 10:16 PM: Information has yet to be forthcoming about the exact nature of the investigation.  However, Glenn Greenwald over at The Intercept has posted this great commentary piece about the situation:

Even the police’s version of events, if believed, raises all sorts of questions. They say Rahim was under “24-hour surveillance” by the FBI Joint Terrorism Task Force, and were monitoring him for at least two years. When they approached him, they had no arrest or search warrant, but instead simply wanted to question him. When they did so, he pulled out his knife, and when he refused to put it away and walked toward them, they shot and killed him…  What was their intention in approaching him this way? Were they wearing uniforms, and — supposedly believing he was an ISIS operative eager to kill police — did they do anything to make him feel threatened?
