The machine is only loud when it is actively scanning a patient which it doesn’t seem like was happening in this case. Otherwise it’s relatively silent.

yeah well i’m assuming that if the gun was “sucked into the machine” from the hands of the police officer, that it would have probably been relatively violent. Generally magnets aren’t very polite.

Also the big button is (in my experience at multiple hospitals) always in a different room behind a box that you have to open.

yeah i would have to know the floor layout of the specific place in order to make that judgement tbh. That was just my first insight on that one though. There’s a non zero chance he saw it walking in, police are generally pretty observant, and these buttons aren’t exactly well hidden either to my knowledge so.
