They where on public property where thousands of other tourist travel. Ridiculous...clearly they aren't spys.
The Greek secret police arrested them because they were taking photos of military installations that are covert, not publicly accessible and are hidden from satellites.
Limnos is a very sensitive place for Greece due to close proximity to Asia Minor, Turkey (the main enemy of Greece).
Although i love Arma series and i played Arma constantly, what the guys from Bohemia did is illegal and not very sensible, it was stupid, they should have asked Greek military to grand them some type of limited license to take photos and under Military supervision.
The law here in Greece is Crystal clear. Signs are all over the Greek islands prohibit taking photos of military installations. I hope the Bohemia guys don’t face charges of spying because then they will go to Greek prisons for many – many years.
and I think they were collecting info that wasn't publicly available? @arsenal1111
