Immigration law does not invade civil liberties. Check points probably should get a better managed system when considering the local US citizens, if the border towns are next to checkpoints. The locals in any border town should never assist any smugglers activities, illegal activities, but don't complain if they get caught doing so. I also don't feel any officer should target or harass any local or accusing anyone without true and good suspicion or showing solid and good sign of intent to smuggle. I feel civil liberties should be considered before anything, especially when we have the civil rights of Pursuit of happiness, Liberties, and freedom given to us by the US constitution. I feel village, township, State, and Federal management should have a good understanding of police being very inexperienced in many areas in life, and all law enforcement should have better management in place. We the people have a joke for a voting system, and this allows for bad management, which allows officers to go less noticed and allows for bad officers to continue to abuse the law to damage peoples records and make it easy to turn normal people into criminals while going through a normal life lesson mistake. It doesn't help when "The People" of our villages, towns, and cites' don't pay attention to the system, don't vote and don't seem to have much time to get involved. The economy is bad, and the system takes advantage of the people being overworked or too tired to get as involved as they should.
