The Mexican army is not a'head' of the drug game

Five human heads were found yesterday in ice chests left beside a road near Guadalajara, Mexico. They appear to be the latest indication of drug cartels fighting for supremacy in the Central Mexican state of Jalisco.
To make matters worse, the Mexican army, which has taken a lead role in attempting to thwart narcotraffickers, is hurting; nearly 150,000 soldiers have deserted the army in the last six years. The deserters left their post in search of higher paid jobs.

Why can't we all just get along?
