The New York Sun made a good point yesterday that even a naturalized citizen or permanent resident (defined in the statute as "United States persons") could arguably become targets due to the probability of visa/imnmigration fraud and not disclosing associations with terrorists.
In other words, it's possible for them to lose their protected status.
This has already been done in many other Islamist cases, and it is very clear even to applicants that naturalized citizenship can be retroactively withdrawn due to lying on an application.
That is exactly what happened to Damra, he was head of the Mosque right here in the Cleveland area! It was/is the largest mosque in the area! He has ties to hammas et al. People here think this matter is over with, but I don't. He was a radical imam in charge of a large mosque, what else is crawling around here?
