Laws, like burglar bars work both ways. If we anticipate making life harder for "bad guys" by putting up legal barriers, outfitting large, well equipped police forces we must expect to find ourselves under their scrutiny and domination. Think about it. Police forces cannot, by law, discriminate. They must treat everyone they come in contact with in the same manner. To them, we are all suspects and must satisfactorily answer their questions. This is why a state like New York, Connecticut, or Massachusetts prohibit anyone from carrying firearms in public. They cannot write a gun control law that only applies to "people who have the intention of committing a crime". They have to write it for everyone in the hope that it will deter those few people with criminal intent. In the meantime people who have no intention of committing a crime, including violation of gun control laws, find themselves helpless against thugs while trying to avoid trouble with the police. See how silly this all is?
The Supreme Court of the United States has made quite a few decisions which should be considered. These decisions were made to protect our liberty and to insure our peaceful co-existence with law enforcement. Several cases have been decided which plainly state that the police have no duty to come to our rescue. This makes sense. There is no possible way the police could be in position to save all people at all times and places. This is why it is the height of foolishness to support gun control. It makes our citizens helpless against attack while our police are not obligated to come to our aid.
The police cannot arbitrarily ask you for your identification. They cannot assume you are a felon, if you are carrying a gun. They cannot "check you out" with out being able to articulate a specific and creditable suspicion. In short, they are supposed to give us the benefit of the doubt and allow us to proceed without hindrance or molestation. These are all good rules for a society wishing to enjoy the fruits of liberty. However they are an obstruction to law enforcement who are charged by their voters to, "secure the borders!, "enforce immigration laws!, "get guns out of the hands of criminals!" With these demands we will only bring restrictions and barriers upon ourselves. As it happens in our airports everyday, we will find ourselves "proving" that we are law abiding more and more often. We will barricade ourselves inside our own nation.
This video shows these constitutional restrictions at work. This driver wishes to be free to travel through an unconstitutional checkpoint . In the end they let him pass without having to prove his citizenship. However, if we do not start reining in these many agencies and police departments it will be the rules changing in their favor and our liberty will fade.
