Maybe by design, depending on what you mean. I think organized crime and state corruption (often hard to separate the two) thrives under all that chaos. Brazil is HUGE and I see many people asking to bring control back to each of the states.

How that would help I'm not sure but it's like the government is isolated in their own safe island and they are in most cases untouchable, or just get a slap in the wrist. I'm surprised how in the poorest and uneducated areas you can get lynched or beheaded if someones yells "thief" or "rapist" (even if you're innocent) but there isn't any acts of organized violence against the government.
