During a speech before a Muslim advocacy group near San Francisco, U.S. Attorney General Eric Holder denied allegations Friday that government anti-terrorism tactics are overly aggressive and border on entrapment. Holder stood behind FBI methods used in recent undercover operations against Muslim American groups. Muslim Advocates executive director Farhana Khera, who invited Holder to speak to the group, said many people feel that the government has been enticing Muslims into terrorism. She said, “We have very serious concerns about FBI surveillance tactics that are used.”
