> There will be a scanner on the airport line that would detect antimatter atoms in quantities of more than a few thousand atoms, which is what you would need to create an explosion.
If I've got a kilo of antimatter in a briefcase, I'm just going to set it off at the scanner then, killing the ~10k people in the airport... and half the city it's part of.
