Dude, I am living in #Venezuela and these "nasty" gangs which you have seen on television, are VERY RARE in real life. The real nasty gang, is the police force. They arm the gangs.
The problem with your reasoning that the police force is the real nasty gang is that a people get the government it deserves. If the police were removed the state would become impotent, but in addition, the power vacuum that removing this gang leads to would likely lead to other gangs growing into the role that the police "gang" played.
