Technically, that would be trespassing and you could do spend your time making those calls. Practically, the cops would do nothing and you would waste your time. Laws don't change by annoying cops.So technically, by law, I can set up a surveillance camera on the public sidewalk running on my property. If someone cuts the corner and steps over my yard, rather than staying completely on the sidewalk, I can prosecute them for trespassing. Everyone that lives in town in WY should start doing this, and call the police every time they see it happen. Demand that charges be filed. Provide video evidence of your airspace being invaded.
