Surely there's a simple way around this?

If everyone in the uk typed certain things into google every day then their super spy computer would crash under the weight.

If specific keywords are a trigger (Isis,bomb making, politician killing, paedo terrorist on holiday in Syria should do it) then loads of people typing this would ruin their surveillance, thus making it all a bit pointless.

Even if they did have the resources to track down the millions of people doing it, you could just say you were pissing about. You could even show them this post as proof that you're not a beardy bomber, just a bit of a rebel that is fighting back against the snooping.

Problem solved.
