Now that you mention it, that kind of does make sense. It seems to be Mossad's MO to make a big scene out of their assassinations. Almost like they're countering what the terrorists do by making the terrorists afraid to travel or even go outside.
From my readings, the Mossad did not usually go in for being elaborate. For the real-life “Munich” saga, they relied on close-range pistol work. The last one in ‘78, Ali Hassan Salameh, was blown up with a car bomb in Beirut. They did get a little more elaborate in that they set up a female agent in a nearby apartment, posing as a crazy cat-lady british widower to observe the comings and goings of the careful Salameh.
The eighties hits on Saddam’s nuclear networkers were also pretty straightforward.
