Over the 1980s the Black Power movement continued despite a decline in its popularity and organization memberships . The Black Liberation Army was active in the US until at least 1981 when a Brinks truck robbery , conducted with support from former Weather Underground members Kathy Boudin and David Gilbert , left a guard and two police officers dead . Boudin and Gilbert , along with several BLA members , were subsequently arrested . M19CO engaged in a bombing campaign in the 1980s . They targeted a series of government and commercial buildings , including the U.S. Senate . On November 3 , 1984 , two members of the M19CO , Susan Rosenberg and Timothy Blunk , were arrested at a mini-warehouse they had rented in Cherry Hill , New Jersey . Police recovered more than 100 blasting caps , nearly 200 sticks of dynamite , more than 100 cartridges of gel explosive , and 24 bags of blasting agent from the warehouse . The M19CO alliance 's last bombing was on February 23 , 1985 , at the Policemen 's Benevolent Association in New York City
