By the sounds of it , it ' s not as if the police are just going to spend hours and hours and hours of browsing through millions upon millions of people ' s histories just for the sake of stumbling across one or two people who may have looked at illegal content . That ' s like the equivalent of knocking on every single door in the entire country , looking for a murder suspect . I ' d imagine this would be used when police are tracking people who are already suspects . Also , haven ' t this kind of thing been in practise for years ? Only now , it ' s officially been legalised . I signed though . This is going to lead to an incredibly selfconscious , paranoid nation . Even when you have nothing to hide , the thought that what you ' re looking at is the knowledge of the government is very unsettling .
