Mossad aren't exactly known for being subtle. Just look at the way they took out the guy they mistook Ahmed Bouchikhi for. Sure, they got their man... along with his four bodyguards and four bystanders. Not to mention the sixteen people injured when their bomb attack on Ali Hassan Salameh went off.

Consequences appear to have been less than five year prison sentences for several accomplices. The murderers were able to escape and could not be extradited to stand trial. Israel paid out <$500k to the families but did not admit responsibility.
