OK, any specific response would require knowledge of a specific locality’s laws. I am hoping there is a generic legal thought behind this query.
Case in point. Last Saturday we were driving (under the legal speed limit) along a city street in a residential area. The street is a significant cross street (two lanes both directions). We noticed ahead on the right side, a police car was parked perpendicular to the street on a private unimproved residential lot (lots of wild grass, no bushes or trees), with it’s front bumper more than 20-30 feet from the street. Sticking out of the driver’s window was a radar gun.
Is this legal? Can the police run radar from private property attempting to catch speeders on a public street? Must the police secure permission from the property owner? Or is it outright legal/illegal?
I ask because some years ago in my hometown (MadCity, WI), the police tried this very same thing, sitting in the parking lot of a funeral home with radar trained down the street. IIRC, someone challenged their ticket in court and the judge not only threw out their ticket, but every ticket the police issued under similar circumstances.
I have a call in with the local city attorney on Saturday’s observation and await their response. In the meantime, I hope some Dopers can shed some lght on this.
