content: Three cops go in, one comes out arresting or protecting the woman. Now there's four or five black dudes in the house and two cops. The guy the two cops are trying to arrest yells "fuck em up" and him or someone else says "lock the door". So someone locks the front door. At this point the two cops are in a very dangerous position and backup can't easily get in to protect them. If anyone in that house had a gun there's a chance they'd both be dead. When the backup police get there they break the windows so they can get in, make arrests, and protect the two stuck in the house.
