I feel I should be bundling posts here, but I'll throw in another. The argument fails on several grounds. First that no crime should deprive anyone of due process. Second, that at the time of the deportation he was not here illegally, no matter what his history, and third that he was not just deported. He was not just sent back to El Salvador and dropped at the airport or something. Even if doing so would have resulted in his immediate arrest and imprisonment by the El Salvador authorities, it is simply not the same thing as what happened. He, and others like him, were extra-judicially convicted and sentenced to imprisonment in El Salvador. The decision to convict and imprison him was made in the United States by the United States.
Hercules has asserted that Garcia is the wrong person to defend, in part because he's such a bad guy that the public will reject the defense and the cause of justice will be set back. The remedy for this seems to be to let this one go, and try next time. I think that's a serious mistake. Next times are tentative and tend to stretch into more next times until it's too late.
