In this particular case the guy knew exactly what he was doing and he knew exactly what he was risking by doing it.
Every time he raised a glass of alcohol to his lips he knew what he was doing and when he was doing it.
He knew his rostered duty time and he knew when he reported for duty that he was taking a great big chance.
Six months in pokey is purely symbolic. Everyone knows that he will only serve a fraction of that time actually in prison and that he is likely to be sent to a comfy country hotel such as Ford Open "Prison".
The "10 year" thing is complete bolleaux, as we all know that it would be an extremely unwise airline employee who would hire somebody like this after a major conviction such as Kyagera's, either within or beyond 10 years from now.
Even a Ugandan or Kenyan airline wouldn't hire this guy, with his track record.
We all know that laws exist for the guidance of wise men and for the blind obedience of fools. Kyagera is a fool.
