BOSTON (AP) — Muslim groups and civil rights activists across the nation Thursday called for greater transparency in a program by President Barack Obama's administration that's aimed at countering homegrown terrorism.Organizers, including representatives from the American Civil Liberties Union and the Council on American-Islamic Relations, spoke out at coordinated events in Boston, Los Angeles and Minneapolis — the three cities where the Countering Violent Extremism program is being piloted.Among their concerns is that organizers still refuse to share basic information about what the localized efforts will actually look like.
