So let me get this clear:
1. You arrive in the US illegally as a child, live there many years, achieve fame (or not). Then you reveal your status. We're all supposed to feel bad and change our views on, well, that little ol' thing called the "law" because of that and acclaim you a true-blue American.
2. You arrive in the US as a child (legally? who knows), grow up there, never really know your country of origin. You commit a heinous crime and are sentenced to death. Time comes for execution fifteen (!!) years later, and suddenly you "discover" that you're not an American and you (and both the Mexican and US [!!!, sadly but not suprisingly] governments) start demanding all sorts of rights based on that.
His last words, of course (thank God Texas doesn't buckle under to pressure), are in praise of the country he never lived in.
Full disclosure: I'm a (legal) dual citizen myself. But I'm not demanding any sort of special treatment. Nor am I (case one) lying or (case two) murdering, it goes without saying.
Edited to add: For another example of non-computing in this case, see here.
