JD,
i would interpret this phrase as protection of private beach properties, not giving the public the right to cross private property to reach a beach, but i would say between private properties should be the walkways like shown on Steve's fotos of the south to access the public area without entering/crossing private property.
interesting theme.
to the OP, the situation been that the guys been on the beach, they did not cross any private property on their way to the public beach(at least as far as my understanding), so as long as they do not appear as a threat for the near the beach private property, as long as they are down at the beach, i would say it is illeagal to show them their way out, the occuring of a private employee(guard/watchingman) on a Public spot(the beach) and armed i would take as a armed threat on my person and the ones with me and take legal actions or pull out my own gun before he has the hand on his one to really threat me and drive him down to the next Marine station with his pump gun in the trunk.
of course the only recommended way is always just to beg off and complain aftrewards, but such should get reported, than more often than more likely there will come the day where some legal action has to be taken to keep public areas open for the public.
i doubt that such really will happen,
the big bucks of a huge resort/private investment area still easily buying laws aso to be 'understood' in their favor.
yes, i understand that a 'tourist area' needs special attention if the country want's to convince tourists to visit and spend their $$$ on the island, i live myself right on the beachfront(25 meters from the Veranda to the Sand) and here thanks god it is public, shaddow areas with little Cana-roof provided and maintained by our residence near the water are accessible for everybody who wanna use them and wanna have fun in the sun on the PUBLIC beach which it is, during weekdays it is very quiet, saturdays and sundays it even can be crowded, that's domnican public life on a free public beach, i like it myself exactly the way it is watching my son in the water with dozens of friends having fun, on the other hand i would assume that 90% of our tourist visitors would not fit in that great crowd/our behaviors to have fun, because to read quietly a book on that beach or take a nap is not easily possible, ha ha.
maybe Sr Guzman can jump in again and provide info about the 'additional' to the old law, the written down 'exceptions/handling rules' for such specific areas, if they exist i don't know, i would be interested in such myself.
as a matter of fact it is handled like that here in the PC area, wide parts of the beaches are not accessible for the public.
