What do you see as the issues associated with people being treated differently within a criminal justice system based on which state they are in?

So basically it a discussion question. In the discussion decided if I agree or disagree with additional rights beyond the constitution being granted to people within a state. What do you see as the issues associated with people being treated differently within a criminal justice system based on which state they are in? What is the rationale behind the your decision? My professor wants me to use the Texas Criminal Traffic Procedural Manuel guide Chapter 9,10.
