Something didn't quite make sense to me
Granted, this is just a movie, so things don't have to be perfectly accurate, but...
Naked Gun 1 and 33 1/3 were set in LA, as that's where Police Squad was. So, how did everyone wind up in Washington, DC, for 2 1/2? Frank's presence was explained by the White House dinner because he was celebrating his 1000th drug dealer killed. But, what about everybody else? Shouldn't that whole case have been left up to the DC police department?
