That is not what happened in Honduras. While an impeachment would have been appropriate, he had not been impeached. Nor was he arrested and then tried. Rather, he was expelled from the country.
FWIW, in no way do I support his actions. In fact, I strongly believe that he should have been impeached for his conduct and prosecuted for such crimes as he might have committed. My single point of contention concerns the integrity of the constitutional process, not whether or not Mr. Zelaya should govern. Unfortunately, the constitutional process was cut short with the coup.
