Actually, Mexico is not the most corrupt.
According to Transparency International countries like Argentina, Russia, Iran, and others have more corruption than Mexico. Luckily SRGE is not operating in those countries. Unfortunately SRGE is not operating in Norway, which tops the list of least corrupt countries.
And you are correct about government officials dropping SRGE if needed. That's what happened to BGL, and SRGE will continue to be a straight shooter in order to stay in good standing with the government..
IMO
Best to all
