On Tuesday, NYPD officers utilized flash-bang grenades to breach Columbia University's Hamilton Hall, where protesters had barricaded themselves inside. The police department reported that the building's doors had been barricaded with chairs, tables, and vending machines, while windows were covered with newspaper.
A flash-bang grenade, when deployed, emits a bright flash and a very loud bang, commonly used to shock and disorient individuals. Video footage shared by NYPD Deputy Commissioner Kaz Daughtry depicted officers searching an office lined with bookshelves after breaking the door's lock with a hammer.
