The extremely short career of an Afghan officer candidate

Guardian:

An Afghan soldier has been killed after opening fire on a foreign trainer fromAfghanistan's Sandhurst-inspired officer academy, meant as Britain's main legacy, just days after its first recruits enrolled for class.

The Afghan was shot after having an argument with a trainer from New Zealand and two Australian soldiers, all three of whom were also injured in the skirmish.

The shooting casts a shadow over the start of the first term at the academy, which has been described as a Sandhurst-inspired complex. An initial class of 230 recruits began training last week, with journalists invited to see them put through their paces and tour the tents serving as temporary classrooms while work finishes on the permanent buildings.

Eventually it could train up to 1,500 men and women a year, with 120 UK mentors supported by instructors from Australia, New Zealand, Norway and Denmark. The brief gunfight broke out after the trainer had visited a nearby building at the Afghan National Defence University site in the mountainous western outskirts of Kabul. The UK-funded National Army Officers' Academy nestles by five other colleges including a foreign languages centre and a sergeants' training academy.

Are Afghans over sensitive to criticism or is the screening process defective for officer candidates?  Neither alternative reflects well on the character of a candidate like this one.
