From what I have heard, they go after your family as well.
If I had anything to say about it would be to assemble a death squad; high trained, highly experience soldiers/mercenaries who's sole mission is the eradication of the cartels. Put the fear back in the cartels. It is a unjust, being a violation of human right and all but it would save a lot of innocent lives.
But the drug trade is far to lucrative for their not to be the amount of corruption that exists. The Cartels have the power and the people who govern Mexico are either corrupt or fearful of the Cartels so violence run rampant. The weak prey on the weak, the strong prey on the weak. It definitely sucks.
These are just my opinions I can be wrong. I don't live there and from what I have heard from the people that did or do is that Mexico is a nice place except for the violence and corruption.
