40 years ago today, the Philadelphia Police Department used a helicopter to firebomb the headquarters of MOVE, a radical collective that was being evicted for what amounted to building code violations. Eleven people died (including five children). The fire eventually spread and completely burned down two city blocks.
Then the remains of those killed, were, for unclear reasons, turned over to the U. Penn Museum, where they sat for decades. https://share.inquirer.com/m7vjmf
