I have actually engaged with relatives of victims of violence. What happens on the ground is that as you move away from the capital of the given countries, you run into territories where there has been a lot of violence or open war, as in the case of Brazil, or an overall lack of state presence. The state has not been there. Police have not been there. The army has not been there except for repression.
The standard practice is that the police show up when the companies need them to show up, but not when the regular citizens need the state to be there for them.
Basically, the affected communities and the indigenous people consider the police or the army to be subcontractors of the large operations. They don't trust anyone with a uniform to be on their side. It's the same thing with the criminalization of protests. The standard practice is to go very actively after the local human rights leaders and defenders, also union leaders, in a very aggressive way, not all the time, not at all locations, but it happens so often that the general perception is that the judiciary is also co-opted and captured by the commercial or economic interests.
