Tallg,
Not that I will pursue with any further report. But the incident on the first flight was far more serious than the one on the second flight. The first flight things became so nasty that, the crew did have to report the incident to the captain, and did announce that security would be at the runway on arrival in Doha, which none of that did happen.
The second incident (this post), it went in accordance with the procedure. The victim (not the aggressor) was transferred to another seat and things calmed down for a while (the aggressor kept causing problems but not with other passengers) so I guess in this case the procedure was followed.
Not on the 1st incident.
But hey, as you said, they are quite OK and it’s not the airline it’s the passengers!

PS. Singapore Airlines, Japan Airlines and Thai Airways, in my opinion, are also better than Qatar Airways!
