Get the police in check

Police are continuing to become more and more hidden with unmarked cars, vehicles with lettering matching the color of the vehicle and vehicles without government tags. They are making their best attempt to stay hidden from the public eye. I believe these things should be illegal due to these vehicles being very easily copied by anyone attempting to impersonate a cop. Police are not meant to hide and harass but to protect and serve. This path is difficult when a citizen can't even find a police officer because they are making their best attempts to hide. I believe police should adopt the same as a few county's have and most European countries already have with silver or white vehicles very well lit and marked with reflective high visibility markings.
