We seem to have a real problem with what should be basic concepts in this country.For example — there’s the concept of the difference between “friends” and “enemies.”True, it was Don Vito Corleone who said “keep your friends close but keep your enemies closer” and he may have meant it, but, let’s be honest. He was a fictional character, and there comes a time when we really shouldn’t be investing taxpayers’ dollars to keep our enemies at all.It all came home to roost in Mo Town recently when a “performer” who turned terrorist came to trial.According to the Associated Press report, “Syrian native Mohamad Masfaka uses the stage name Abu Ratib” and he is “accused of concealing ties to a terrorist group has pleaded guilty to making false statements during the U.S. naturalization process.”He was part of a “terrorist group in 2001, saying it had provided money and support to Hamas.”And this is how his current situation is described: “The U.S. attorney’s office says Masfaka likely faces 10 to 16 months in federal prison before being deported to Syria. He’ll be sentenced on Dec. 14.
