From Haaretz.com (Mazuz is the Israeli Attorney General; my emphasis in red):
"The detention of Hamas parliamentarians in the early hours of Thursday morning had been planned several weeks ago and received approval from Mazuz on Wednesday. The same day, Shin Bet Director Yuval Diskin presented Prime Minister Ehud Olmert with the list of Hamas officials slated for detention."In other words, Israel used the Palestinian attack on the Israeli military post as an excuse to do what it was looking for an excuse to do, arrest a democratically elected government and destroy Palestinian access to electricity. And the world sits back and lets it happen.
