Daylight hours and not in a high crime area, so yeah completely different environment...2AM in East STL I'd expect to be asked to slowly exit the vehicle while keeping my hands visible, maybe even drawn down on while exiting considering the variables. I'm a bit surprised they didn't have your SIL at least get out of the car so they could check things out, especially if she was still dressed in costume for the sting. Gotta believe that full disclosure of a weapon in the car starts things off on the right foot.
