its not a simple 1 dimensional issue. Civil liberties will be eroded by extending surveillance measures and at some point (different for everyone) the boundaries of acceptability will be exceeded. If we live in a truly free society which is what our powers that be are supposed to aspire to, then they have already sacrificed liberties in the name of security.

Does security infringe on how we carry out our day to day lives, no not yet. Does living in fear that a madman will shoot up a theatre or bomb public places infringe on or freedom, no not yet. The latter is probably still true because the security measures we have are successful, we know many threats have been thwarted before terrorists got a chance to go wild. What would have happened without those surveillance measures?

So, we have a balance at the moment that seems to be quite effective. If terrorists start beating the current measures, and they start to become successful, then we should up our game and increase surveillance, but at the moment, as terrorists have had very little success here, I personally don't see a need for any further measures.
