If anyone wants to understand why Mexico has such problems with corruption, it's LITERALLY because their Constitution actually PROHIBITS prosecuting presidents, sitting or retired. That has meant Mexican presidents can and thus generally do whatever they want, legal or not.

I want to add that the corruption goes up to and includes murder. Most Mexicans believe that presidential candidate Luis Donaldo Colosio Murrieta was assassinated on the orders of the PRI and President Salinas: en.wikipedia.org/wiki/Luis_Do...

The US AIPACracy corrupts all politicians. Mexico at least does not have AIPAC that bribes all members of Congress. The ones who don't want to be corrupted "die" (or their families).
