I cannot make myself believe world's and especially mid-east's most feared inteligence service making mistakes in this level (Security cams ha? Who knew!). This case is more like a message telling "we come, we find, we kill your leader wherever he is and btw don't forget to comment us on Youtube". That's why I called it a stunt.

Hotels are full of security cameras these days. That's perhaps why the assassination victim thought he could travel to a hotel safely even though he surely had deadly enemies. The story, which is worth discussing among hackers, is how the assassins circumvented the security cameras to operate in what was, as it appears, a foreign country for them.

After edit: this quotation from the submitted article, "The door on al-Mabhouh’s room was latched and chained from the inside, and there was no blood evidence," shows more tradecraft than I have for leaving a modern, secure hotel room and ensuring that the assassination scene will yield little evidence and not be discovered at first.

Did it not enter your mind that this video comes from Dubai security services and not Israel?

The real question is the motivation of Dubai in making and releasing this video. I highly doubt that it's as an advertisement for the mossad (even if it may end up coming off as such).

Somehow "Dubai security services" sounds like a joke instead of a beacon of Arabic intelligence to this mid-eastern ears of mine. Thus I think this whole thing ended up as a Best of Mossad episode.
