When the government can’t protect them, they pick up weapons and fight back on their own.
The situation between drug cartels and government forces is a violent and often chaotic one in the country of Mexico. Tens-of-thousands of people have been killed so far and many more will likely die before the problem has achieved resolution.
Some groups of people, left by the government to fend for themselves, have decided to take matters into their own hands. When they can not get the government to send in soldiers to protect them, they simply pick up their own weapons and fight the drug cartels themselves.
