Hi,
We can't say that the Helicopter was trying to smell all the dope in there so they could arrest someone, so it makes me wonder what a police helicopter was doing on top of a bar, unless they knew that some dope deals were done on top of the roof of the building?
The "coincidences" are just too weird and off the wall!
Either that or these guys were playing Chuck Yaeger? And they lost and didn't have their slide ruler with them! (If you never read that, you must ... fun book and lots of hilarious moments, but none more surreal than the slide rule moments!)
