I am 18 and was recently at a party in a basement. There were many people over 21 and they went to the door when the police arrived. They had no warrant, so the homeowners refused to allow the officers to enter. In response, the officers kicked down the door.
As I understand it, police need either a warrant or reasonable suspicion AND exigent circumstances.
Even if they can prove that they had reasonable suspicion, there were no circumstances that would be categorized as exigent circumstances. Nobody was in any danger, there was no indication that evidence was at risk of being destroyed, no crime was visibly taking place, no felons were in the area, no danger was present, and there was no clear evidence that any minors were present.
The police came in and wrote 35 MIPs
