Profiling for Non-Residents

Profiling, the extrapolation of information about something, based on known qualities.

Profiling is illegal in Minnesota. Follow me on this one for a second on my way to work I take an expressway from my city that allows me to quickly by-pass a city on the way to the city in which I work. Every day there are cops from the city I by-pass on the expressway pulling people over for speeding.

Since the expressway is only used by people who do not live in that city to bypass that city. Couldn’t I make the agreement that by conducting that speed trap they are profiling people who are not residents? Hence profiling just by the nature of where they are conducting the operations? Making the process of a speed trap illegal?
Since 68% of the speeding tickets issued by this city are issued on this expressway unfairly targeting non-residents couldn’t a case be made to overturn all speeding tickets issued since the cops are profiling for non-residents?
