The Brazilian government is actually very chaotic, and these officials are originally a group with the highest interests. Although drug traffickers are rampant in the slums of Brazil, they don't do much, and the Brazilian government doesn't really want to fight them. Drug dealers are definitely not just strongholds in Brazil, but almost chain groups all over the world. If the Brazilian government really uproots these drug traffickers on its own, it will really infringe on the interests of these drug traffickers, and it is likely that there will be a great counterattack and the government's losses will be more serious.
In addition, the development of slums in Brazil has been very different in recent years. Not all of them are poor, but there are many people who can't be provoked. These people are United and the Brazilian government can't beat them at all. If it can defeat it, the Brazilian government will destroy it. So the internal force of the slum itself is very complicated. Some of these drug dealers belong to major forces, and once eliminated, they may infringe on the interests of some of them. And the strength of the Brazilian army and the ability of the government are really not so good. So even if drug dealers are rampant, the Brazilian government is unwilling to take action.
If you want the Brazilian government to make up its mind to eliminate drug traffickers, the first thing to do is to understand the chaos within the Brazilian government and then retrain the army. Otherwise, it is impossible for such a Brazilian government to make up its mind to crack down on drug traffickers.
