Eyad Abu Arga was arrested and put on trial because he was spying for Hamas. His sentence is expected to be 30 months in prison (probably because he is Australians and has diplomatic protection. If he was a Palestinian only, I would expect a higher sentence). Abu Erga was looking for new technologies to improve Hamas's rocket capabilities, and for ways to expose phone tapping. Phone tapping is a real problem for Hamas as it has little secure ways to communicate; this weakness enriches Israel's intelligence and has contributed to its policy of target assassinations. Eyad (photo below) has been recruited by Hamas in Saudi Arabia; the Australian news story is below his photo.
