There's been a change since the late 90s away from practising barristers being MPs. It used to be that barristers would be in court in the morning, see problems with legislation, and go to Westminster in the afternoon to fix them. Now of course the media, and parties that never had many barristers in them, demand MPs work "full time" - which means there is far less legal expertise available in drafting and scrutinising legislation. That's why things like the Terrorism Act happen. The name gets politicians to vote for it, but the contents is overlooked and full of powers that are not scoped to terrorism investigations.
