UK border cops can seize and retail all your data without suspicion or charge

Yeah my wife is currently freaking out about going to and more coming back from canada with her laptop. I told if she is that freaked then put your data on a server that you can get to remotely then use a throwaway laptop with a clean OS install on it. But honestly we profile as boring white suburban family and the most we get is an extra question about booze/guns/tobacco/anything expensive bought on occasion.
