Let me give you a history lesson; the people you call "drug traffickers" were actually formed as guerrilla and is still called a guerrilla today (FARC and ELN groups); to start a revolution against the government, unfortunately it didn't go so well so the years flied by and they slowly became a rural mafia that kidnap and kill anyone that gets in their way and had long forgot what their purpose is. Another situation that can happen in any country, including America. So yeah, you are very naive about the possible conclusions of an armed revolution.
