Just beautiful. Life imitates art -- this is the stuff we usually see only in movies.
I love the use of the “Do Not Disturb” sign.
First, this guy was “disturbed”: in fact, something of a psychopath.
Then they came into his room, and again he was (in a different way) disturbed.
And then they leave that sign.
I think that this job was done very neatly, and even very humanely.
If this was Mosaad, they did a good thing. If it was someone else, well maybe they did not have such justifiable motives, but they also did a good thing inadvertently.
