Aviation doesn't exist a bubble. Many criminal activities can be carried out using commercial aircraft.
To suggest that all that matters is stopping aircraft from blowing up is very short-sighted.
If a terrorist, using dodgy documents, takes a commercial flight from A to B so that they can commit a terrorist atrocity, wouldn't it be a good idea to intercept that terrorist before they can carry out said atrocity?
It is simply not acceptable to suggest that AVSEC has no role to play in crime-fighting or ground-based terrorism.
