Because Poliscan gives such little warning its hard to take time to analyze and filter it without risking a chance of it being a real threat. If you know Poliscan is not in your area you can turn it off. I have only seen it once in MD and we have a ticket to prove it since we had no rear protection on the vehicle. For those in Australia where it is very common dealing with some false alerts is the only way to deal with the issue.
