Homeland Security Was Destined to Become a Secret Police Force
Related to these mysterious federal agents in unmarked cars, I've often wondered how private citizens are supposed to protect themselves against someone impersonating law enforcement.<p>In this case, the 'officers' were not even dressed as law enforcement, and either way, it is not very difficult to produce a reasonably convincing replica of a uniform. How can you make sure that you are dealing with actual law enforcement, when you submit yourself to them, they cuff you, take your stuff, drive you away, etc.?<p>"Can I see your badge?" doesn't seem very effective, given that a badge can easily be faked, but more importantly you'd probably, for good reason, be too afraid to even ask. Is 
America really such a police state now that you are just supposed to submit to anyone in a uniform? And does this not seem ripe for abuse to everyone else?
