Britain already has the most CCTV cameras per person anywhere in the world. Now they're adding these, they have laws regulating Anti-Social Behavior, they are trying to implement identification cards for the entire population which will contain all the biometric data, and its probably not a big jump to say that eventually they're going to install tracking chips. If its ok to watch everyone in public then it must also be ok to track everyone's movements in public right? I mean you have nothing to hide if you're not committing a crime. Then maybe we'll record all you cell phone calls you make in public, and then perhaps we'll install CCTV cameras in the homes of registered sex offenders and other criminal types. Then homes under investigation for child abuse we'll install cameras there also. Hm...lets add speakers to the CCTV cameras so we can listen to peoples conversations in public. And then its not such a long step before cameras are in homes and you have ubiquitous surveillance. And guess what? Everything I've just mentioned has already happened other than the tracking chips, they're already put cameras in the homes of criminals and people investigated by child services.
Once we give the government sweeping power to watch us, who is going to watch the government? Are we simply going to trust the government not to abuse this power? To self-regulate? Who watches the Watchmen? Why are you so eager to give the government such vast unregulated power and leeway?
