  Within limits. They need to be protected. But security precautions can be
carried too far, what some call `overkill'. (Like e.g. killing all Great White
Sharks because a few are maneater.) How well do ancient wrecks survive round
Italy where there are not all those Greece-style restrictions?

  >> ... cases of UK naval divers attacking sport divers who they found
underwater while on operations in non-naval sea areas...
  And I don't thank the UK navy for keeping secret their nitrox technology and
discoveries for so many years from 1945 until civilian divers eventually had
to laboriously re-tread the same ground much later as if it was something new.
<Then> the UK navy said that it knew about nitrox all the time. And in all
that time I wonder how many patents for automatic mixture rebreathers were
requisitioned by the UK Ministry of Defence and kept secret away from all the
use that civilians could have made of them? (Compare the well-known `Lokata'
small-boat navigation aid: the MOD tried to requisition <that> patent, but
its
inventor refused and went public and started a row about the matter.)

  >> In the 1970's I read of ... French diving police ...
  Sorry. It's partly that a general atmosphere of officials being able to come
up and demand to see papers at once, and powers of arrest and seizure at sea
on site and even underwater, and the like, irritate me and smell of turning
the sea into a police state, which is one of the things that people go diving
to get away from.
