There is one interesting connection:
Many of the "escorts" are ex, current, or to-be law enforcement and/or millitary. Many of them have been (or working on being) employed by special forces, DEA, FBI, CIA, ICE, DHS, and private military contractors (a.k.a mercenaries: Blackwater).
When i was escorted, one was a retired LAPD detective, another was an ex-marine preparing to ship out to columbia on some obscure lettered agency assignment in a week, the driver on one leg was an ex-ICE agent who was shot and retired, and the driver on the other leg of the trip was an ex-army ranger who was trying to get into blackwater.
