this isn't how people case places for a robbery, if you had time to notice them and grab the plate off the car, they would have something tying them to the scene. more likely this is someone surveiling the house for another, possibly legitimate reason. maybe an hoa member looking for infractions, private investigator, or local pd detective. odds would also be that they wouldn't park in front of the object they're surveiling, so you're just annoying them gang stalking another anon in your neighborhood
