I read the entire
RI State Parks regulations document this morning after posting that, and you're right, though I did not find any mention of an exception for SCUBA divers. Where did you read that?
The posted signs all along Brentons Point also state, "Keep Off Rocks", are they going to start arresting surfcasters for ignoring those as well?
Section 30 states that the maximum penalty for violation of State Parks regulations (with 2 exceptions in Section 26) is not to exceed a fine of not more than $100. Why was the guy arrested instead of just being issued a ticket? There must have been extenuating circumstances that we're not aware of.
I hear what you're saying about the rescue people being put at risk unnecessarily. However, if someone else called in a "rescue" that was not necessary, isn't that the fault of the person who made the unnecessary call, not the swimmer who obviously had no trouble getting back to shore safely on his own? I've swum out to Seal Rock myself several times. It's only 0.38 miles, and not a tough swim at all if you're properly equipped. I wouldn't consider myself a "dimwit" for doing it either, as there is some good fishing around there at times.
