BOSTON (AP) — Boston's Muslim community has been once again thrust into the spotlight as the death penalty trial of convicted marathon bomber Dzhokhar Tsarnaev nears its conclusion amid rising concerns of terrorist recruitment in America. Newspaper op-eds, advertisements and social media posts have highlighted connections between Boston-area mosques and terrorists and suspected terrorists, despite efforts locally to denounce them. Boston is also one of three cities — along with Los Angeles and Minneapolis — where the Obama administration is piloting a controversial new program to tackle extremist group recruitment before it takes root. "Blaming an entire mosque just based on a couple of radical people that don't represent them really is unfair," said Rania Masri, of Quincy, just before Friday's prayer service at the Islamic Society of Boston Cultural Center, a towering brick mosque in the city's Roxbury neighborhood. In February, Americans for Peace and Tolerance, a Boston-based nonprofit group, took out a large ad in The Washington Times featuring pictures of the Tsarnaev brothers and other terrorists or suspected terrorists with alleged ties to the Islamic Society of Boston and other area mosques. A few recalled a February incident in nearby Revere, where threatening, anti-Muslim notes were scattered near a subway station, prompting law enforcement and faith leaders to condemn the actions in a community forum.
