The expediency of police business supersedes it. Therefore, if many police departments around the country have any excuse whatsoever to stop people and check their papers, they shall do so. Their charter mandates that the National Safety Council be nonpolitical and not contribute to or otherwise assist any political party or candidate. They do, however, support strong people controls by any means necessary. Also, nothing in their charter says they cannot receive money from interested corporations.
Insurance companies come to mind right off.
Other socialist-fascist groups intending to control every little thing in the lives of the American people also come to mind. And so it is that the National Safety Council is the group most instrumental in bringing us those police roadblocks all over the country. The common seatbelt is the current excuse for violating our right to liberty. Buckle up or be fined. The implied threat, of course, is they if you do not accept being stopped and questioned, you will be chased down until you crash.
