The Video footage of the Dubai murder

I watched carefully the video footage of the dumb Israeli terrorists in Dubai. I don't want to play Sherlok Holmes, but notice the segment when the Hotel employee is escorting Mabhuh to his hotel room. At one point, she looks behind her and spotted clearly the two dumb Israeli terrorists. But instead of stopping to let them pass, she continued to walk thereby allowing the dumb Israeli terrorists to spot the hotel room of Mabhuh. I dont know what this means but it could mean something.
