The poachers as game keepers model is not totally mad.
It is mad to assume that you will lure a professional tomb robber to a carreer as ticket taker but such people are not the entire, or I suspect the main problem.
Much damage is more casual. In parts of the Middle East culturally, though not legally, the local tribe believes that it owns everything in its territory.
Thus there are two bedouin tribes that "own"
Petra - I forget the details which I once heard but one "owns"
Petra and one "owns" one of the access points. If such groups are ignored when the State makes its plans they will loot what they believe is theirs. However, if they are given employment - not the jobs that require specific qualifications that they may not have but all of the "unskilled" jobs - and the right to sell food, water, souveniers, etc. they are often won over as allies.
I remember visiting
Pella, a fantastic site overlooking the upper Jordan. When I visited it it was in a restricted
military zone and saw no tourists or foriegn visitors. Nada. There were no digs going on, no museum, just a gate house. However, there were a couple of locals employed sell tickets and otherwise stare off into the distance. With entrance fees of about $1 and no visitors the State obviously lost
money on these guys salaries but it bought protection and
security - not so much their vigilance but paying into the local community.
Anyway it obviously won't fix all ills,
nor was Andrew claiming it would, but it is yet another of the many models of archeological asset management to explore.
