Stop moaning about this sort of stuff and just get on with it. Legislation such as this is there to proactively prevent harm to the majority of the population - its no good reactive to a terrorist incident or major security incidents as the damage is done at that point.
The risk of a few people in a total population of 65 million having their civil rights ever so slightly infringed in order to provide a safe environment for the other 99.9999% of the population are negligible. Get over it.
