Let me give you a little scenario to ponder:

An innocent man who offers no suggestion that he is a threat in any way, is murdered on a London train with 7 point blank shots to the head of the victim over a 30 second interval by an UK police officer with Scotland Yard's elite CO19 gun squad.

In a sane world, what should happen to this officer? Reprimand? Dismissal? Jail time?

Think again:

De Menezes Gun Cop To Train Sky Marshalls

ONE of the officers who shot Tube blunder man Jean Charles de Menezes is to train new British sky marshals.

The armed cop, in his 30s, has been picked because top brass say he has "proven ability to act swiftly and decisively" in emergencies.

"We need the best to counter the very real threat posed by international terrorism.

"Sky marshals have to act quickly and decisively in any situation.

"They have to be ruthless in bringing down potential terrorists before they can bring down an aircraft."

All UK police forces have been told to send firearms officers for the eight-week course because of the heightened terror alert.
Hang on...I feel a quote from Lobaczewski coming on:
In a pathocracy, all leadership positions, (down to village headman and community cooperative managers, not to mention the directors of police units, and special services police personnel, and activists in the pathocratic party) must be filled by individuals with corresponding psychological deviations, which are inherited as a rule. However, such people constitute a very small percentage of the population and this makes them more valuable to the pathocrats. Their intellectual level or professional skills cannot be taken into account, since people representing superior abilities are even harder to find.

After such a system has lasted several years, one hundred percent of all the cases of essential psychopathy are involved in pathocratic activity; they are considered the most loyal, even though some of them were formerly involved on the other side in some way. [...]

[T]o mitigate the threat to their power, the pathocrats must employ any and all methods of terror and exterminatory policies against individuals known for their patriotic feelings and military training; other, specific "indoctrination" activities such as those we have presented are also utilized. Individuals lacking the natural feeling of being linked to normal society become irreplaceable in either of these activities. Again, the foreground of this type of activity is occupied by cases of essential psychopathy, followed by those with similar anomalies, and finally by people alienated from the society in question as a result of racial or national differences.

The phenomenon of pathocracy matures during this period: an extensive and active indoctrination system is built, with a suitably refurbished ideology constituting the vehicle or Trojan horse for the purpose of pathologizing the thought processes of individuals and society.

The goal- forcing human minds to incorporate pathological experiential methods and thought-patterns, and consequently accepting such rule - is never openly admitted. This goal is conditioned by pathological egotism, and the possibility of accomplishing it strikes the pathocrats as not only indispensable, but feasible. Thousands of activists must therefore participate in this work.
I know what you are thinking, "this is very dangerous!" What if this sky marshall (or one of his students) gets trigger happy when some passenger looks at him the wrong way and tries to unload 7 bullets into his head...might not one of the bullets puncture the cabin and threaten the lives of all passengers and crew?!

Put you mind at ease:
"Sky marshals will be issued with Sig Sauer 9mm pistols, with special bullets which do not ricochet and damage the aircraft's fuselage."
