Ethnic profiling isn't just racist, it's bad, counterproductive policing that helps terrorists. The good news: with proper training, security services can target people on the basis of evidence, not colour, and do a better job of keeping us safe.
Opinion shapers don’t just develop new ideas that may become social rules. They also create new information on how existing rules are being applied in practice - something called democratic accountability. To do so they need privacy - here is why.
Why? Because it's useless and it's dangerous. Only traditional methods of gathering intelligence have helped security services stop terrorism. Mass surveillance, which doesn't produce results, is draining resources away from tools that actually work.
