Ignore me! You may have the feeling that you're being watched. Don't worry about it. Pay no attention to the men behind the curtains. They're doing their best to get to everyone. It just happens to be your turn.
Yes, maybe it would make more sense to exercise their surveillance powers on those most likely to be involved in criminal activities. This might mean doing actual investigative work and following logical leads, but sometimes the temptation is too great to just take a swing at the low-hanging fruit. This means there's a stronger than nil statistical chance of violating the privacy of people without legitimate cause.
You want me to trust incomparable surveillance and intelligence gathering power in someone else's hands? I'm willing to trust Santa and Superman (and maybe a few of his friends) with that sort of resource, but that's a pretty short list. They each have a proven record, though, that proves their judgement can be trusted.
The illusion of "oversight" is fantasy. The people who worm their way into government continue to prove that they will do what they can, in the name of expediency, to circumvent any oversight or control procedure we put in place. This automatically means that we have lawbreakers (scofflaws, if you prefer) making assessments on the activities of anyone they choose to pay attention to. Convenience and security are not worth the sacrifice of Freedom.
Checks, balances and oversights are created with the intention of preventing abuses of powerful tools. Government servants are taking it upon themselves to decide that they don't need the safety measures, opening the processes they're using to abuse. Show us that no one has ever been wrongfully prosecuted by the IRS or the FBI or any police agency, or that no one has ever been harmed by the medical system and we'll talk. Otherwise, safety measures are demanded for virtually every potentially dangerous product in our lives, why not surveillance/enforcement toys, too?
On top of all that, it seems that 69-year-old Peter Mayhew (Chewbacca, smuggler) was stopped in Denver by the TSA because of his suspicious cane. Are they still looking for tall, old foreign guys? Have they not heard that Osama Bin Laden was taken out of action? Have they merely tipped their hand, revealing that they side with the Galactic Empire? Well, like they say, we're not paranoid enough, so I guess we shouldn't be surprised that it happens on both sides of the line. It'd be nice, though, if our government servants would remember that they work for us, which means we should all be on the same side of the line.
