What message did CIA chief take with his hand in Kurti's pocket?

Many suggestions were given as to what this action of Burns might mean, but American professor Edward Joseph recommends that there be no too much analysis.

It's interesting and I've also noticed Burns was holding his hand in his pocket. It's interesting, but we should be careful here and careful and the audience should be careful. We should not analyze too much. Let's say: Look how Burns held his hand in his pocket and that this would mean some kind of signal. That would be excessive analysis, but what we can say again the timing and moment of the visit”, Joseph said in RTK, adding that it took place at a time of high tensions and Burns is directly linked to these extremely serious negotiations.
