Sorry, but he's actually an American pretending to be Irish - in other words, one of your own.
there is a surprising amount of suicide deaths around the Smoleńsk catastrophe - many among military personnel - of which the mainstream media are rather shy to report
I'm not surprised. Given that Smolensk exposed a culture of sloppiness, half-heartedness and general incompetence - I'm not surprised that military guys saw suicide as a realistic option.
Commenting on the thread without having read the articles linked to in the OP as well as including a pissy remark about another forum member.... Way to go Harry!
So what's the story?
Not much to say. He's been caught indulging in illegal activities (which, for a military man, means his career is over) and obviously was making some sort of statement with this little attention-seeking stunt. He'll now be retired on medical grounds, and will no doubt join PiS later.
