Apparently, there was only one assailant last night and look at the death toll. The damage just one individual can do is horrifying and you have to feel some sympathy with the security services when you consider just how soft these targets are with a population of tens of millions to police/protect.I know what you're saying and I agree that powers have been mis-used in the past. What I was advocating was proper, legit intelligence gathering to monitor all, in order to target the people doing this type of atrocity. We surely can't expect our security forces to protect us but not give them a powerful tool to help them?
