Yossi Melman says, about the Dubai operation:

the gravest danger of all is that someone in Israel's
talkative society will identify one of the operatives as his neighbor
or acquaintance from the past, and will not only hasten to tell his
friends about it, but will also post it on the Internet.

Half of the London Jewish community immediately recognised the British names on the list of suspects in the killings; if the Mossad is indeed to blame, surely half of Israel recognised the pictures (disguises notwithstanding).
