Of course, the police can get a court order but what a waste of public money in order to do that.
Yes, Tory MP Heather Wheeler thinks that for the police to obey the law — specifically, law designed to protect us from tyranny — is a waste of public money. If she's consistent in her principles (assuming she has any), then she must think the same about having to get a warrant to search your house. That, or she actually has no idea what she's talking about and is disastrously unqualified for her job. Tough call.
As I may have mentioned before, the problem with the Tories is that they're authoritarian bastards.
