I don't have a problem with CCTV here in England (speed cameras are a different matter grrr). CCTV can help catch criminals or at least identify them like the London suicide attacks.

However they don't seem to do much to deter drunken yobbishness and street crime which if reports are to be believed are at epidemic proportions here.

DNA sampling - fine for criminals convicted of serious crimes. If you're an honest citizen then there's just no need for it.

Sadly I fear it's only a matter of time before we're all chipped and tracked from satellite!
