Like you, I can be a cynic, I can read between the lines, I can speculate. When the news stream is limited, and there is a lot of noise, I don't do any of the above.
The real "risk" here is, press and citizens, jumping to false conclusions.
The head of a sovereign state was forced to turn around his plane and land at an airport, then the plane was searched against his will. What false conclusions are you talking about, these are facts, not conclusions.
After the plane was already searched in Austria. Doesn't seem to be much risk of letting them land at that point.
