They don't? Let's compare some facts. In Mexico, town mayors, elected officials, police chiefs, judges and LEO are often killed for standing up to drug cartels or refusing to be bribed. In Mexico, drug cartels have access to military grade hardware like RPG, 50 cal HMG, grenade launchers and plenty of automatic assault rifles. These folks have no hesitation to take on Mexican army and police. Some cartel leaders and members are in fact former military and police who decided to switch side for money. Is this happening in US? If so, it is certainly news to me.
