Following Pamela Geller’s “Muhammad Art Exhibit and Cartoon Contest” in Garland, Texas, at which two armed attackers were shot and killed, U.S. Marine Jon Ritzheimer has organized a “Freedom of Speech Rally” Friday night outside the Phoenix mosque once attended by gunmen Elton Simpson and Nadir Soofi.

New York Times foreign correspondent Rukmini Callimachi had embedded a tweet which listed Ritzheimer’s name and home address, but the account has since been suspended.

It would be wise to take threats against Ritzhimer seriously, though. ISIS jihadi Junaid Hussain, a young hacker who, according to CNN, may have played a role in inspiring the Garland gunmen through his tweets, has urged attacks on Friday’s event in Phoenix.

Word is that not only are police preparing themselves for trouble; armed bikers will be on hand as well.
