A terrorist carrying enough liquids to create an explosive goes through security at London Heathrow airport. Most of his liquids are confiscated because they are in containers larger than 100ml, and the passengers on his flight are saved.

The next day, ten terrorists carrying between them enough liquids to create an explosive go through security at the same airport. They are let through because their liquids are in containers smaller than 100ml. Thousands die and I still don’t get my shaving gel back.
