cost effective security

[dsrtao]

more air marshals have been arrested since 9/11 (for crimes like smuggling explosives, domestic violence, drunk driving and human trafficking) than the number of people arrested by the marshals. The $860 million spent on the service amounts to about 4.2 arrests per year, at a cost of $200 million per arrest.
