I don't disagree with your assesment of pot hunters, and there are certainly correlations that can be made to some past and even present shipwreck salvors. My problem has been with the broader generalization of all for-profit salvage companies based on the worst works of the worst few. Lets be honest, if we judged all archaeologists on the ethics of the worst 1% of them, they wouldn't look so good either. I believe that is called stereo-typing and its been going on in the shipwreck community for decades. We as a group are not bad people and we don't have bad intentions. I wouldn't sleep well if I felt that I hadpersonally damaged or destroyed an important part of the archaeological record. The only way you and I differ is that after I properly record, collect and conserve the artifacts (a VERY expensive proposition) I believe that when you find and record excesses of a particular artifact (50,000 identical silver coins), it is OK to monetize a portion of that material as long as it funds further research, exploration, conservation, whatever. I don't think that is such an absurd proposition.
To be fair, it is a very small percentage of archaeologists that maintain the narrow-minded views I describe. An unfortunate truth is that these are the ones lobbying the law-makers for an end to private sector salvage. The scientific/academic end of the meteorite community once considered outlawing private meteorite hunting. When they looked into the findings, they realized that more than 80% of the specimens they had to study were found by individual meteorite hunters. To me, a serious scientist would jump at the chance to have an army of well equiped, well funded private groups out collecting data for me. Even if you loose some material and get a few errors in your data, its better than never having the funding or the man power to go and discover the site.
I only posted Gary's email to find out if anyone here knew who he was....the fact that his email (from a sealed case according to Gary) is circulating though the archaeological community is interesting.
