With the new CT scanners you will be discouraged from doing this, viz. unpacking your bag. With the legacy scanners then it was / is a requirement to remove liquids, PCs, tablets and more complex electronic items. The main cause of secondaries was / is failure to do this. CTs change the game here, and are in North Flight Connections. The liquid restriction goes to 2 litres per item, for example.
