I was in that situation many years ago. SWAT rolls up on me and a buddy, sleepy Sunday summer afternoon out in his yard - suddenly police chopper overhead and 12 cars screech up from every direction, packed with insanely amped cops - who pop out with every gun drawn on us and cops screaming at us to “get on ground” - AND - “ turn around NOW and back towards my voice”. I just froze with hands on head and waited til a lull in screaming and said “I can’t do both, so which is it?” Slammed to pavement and pretty much roughed up for 10 minutes. Turns out a serial murderer was on loose and I “fit the description” and neighbors called it in and said I also had a gun. I didn’t match or have a gun but nearly got iced anyways. Funny story now, but it almost ruined a pretty good lsd trip.
