The law was altered recently to allow teachers to search.

Details here.

Customs officers for example also have such powers. If you refuse a customs officer permission to search you, they have to get a warrant. Even if they have found something in a suitcase for example which is the usual trigger.

But I wouldn't worry about it - Lizzie has forgotten this one now and is off on another troll.

To Villan off topic - Blade of course. Don't care who beats the Shammers.
