Anti-Semitism and repeated efforts to censor speech seem to be the hallmark of organized Islam in this country. Take this effort to silence an invited speaker on a California campus.

California police reportedly made 12 arrests on Monday after a speech by Israel's U.S. Ambassador Michael Oren descended into chaos.

Hecklers interrupted Oren's lecture at University of California, Irvine, over 10 times, shouting "killers" and "how many Palestinians did you kill?"

Oren took a 20 minute break after the fourth protest, only to be interrupted again by young men yelling at him every few minutes, local press reported.

Hopefully any students among the arrestees will be expelled for their blatant attempt to limit academic freedom on campus.

And by the way – there is only one proper answer to “how many Palestinians did you kill? It is “clearly not enough, because the Palestinians continue engage in acts of terrorism against Israeli civilians.”
