mulberry in Mexico that is the case, the narcos go by the forces of order and say, you or take our money or our lead.

So many honest cops accepted to take money because they don't want their family, their friends and family are killed, and in the worst way.

having said that, the Mexican state would not have to declare war against the cartels.

in a documentary I saw that many honest and motivated people to fight cartels are far from the places of command, not to mention the political class is corrupted through and through.
The drug traffickers also may have better weapons of federal forces, and have a lot of moneythat don't need to count them, but weigh them directly.

I hope, however, that the violence of the cartels that is becoming scary make that those who must do their duty,do it.
