Because if there is evidence on the phone and I turn it back to the traveller, there's a possibility that the evidence will disappear. Our officers will deactivate the Wi-Fi, any network connection. When it's on airplane mode—you've travelled—there is no cellphone provider, no Wi-Fi, there's nothing. It's only what's on the phone. Then the officer will go through the phone, depending on what he's looking for, based on what he was able to gather during the interview with the traveller.
