The man claims to be "embarrassed" by what he has done. Good -- he can be embarrassed for multiple decades behind bars. Terrorist violence against Americans of any religion, ethnicity, or creed is absolutely unacceptable and should be met with the full force of our justice system. I'm glad they caught the guy, and I look forward to him being sentenced. Good riddance.
UPDATE: According to the Daily Beast, the man in question is actually a Messianic Jew -- which is to say, not a Jew at all. Good news for Jews; does not alter his scumminess in the slightest.
