Terror Victim Family's Lawsuit: ISIS Rise 'Would Not Have Been Possible' Without Twitter

The widow of an American terror victim wants Twitter to answer for the sea of terrorist propaganda and recruitment pitches that flow through the social media network each day.

But the microblogging giant is trying to get Tamara Fields' lawsuit tossed out of court, arguing their network is protected by free-speech provisions and no one can prove that the propaganda posted on the site contributed to her husband's murder.

The attack on a Jordanian police training facility happened Nov. 9 -- a decade to the day after a trio of coordinated hotel bombings orchestrated by al-Qaeda in Iraq killed 60 people across Amman, including at a wedding.

Two Americans, one South African trainer and two Jordanian translators were killed when Capt. Anwar Abu Zaid, 28, opened fire. Two Americans, a Lebanese and four Jordanians were wounded. Abu Zaid, who worked at another training facility but handed in his resignation a few days before the attack, was killed by security forces.

Jordanian officials said Abu Zaid had a Kalashnikov tucked in a bag along with 120 bullets, and a pistol with 31 extra bullets. First Abu Zaid prayed at noontime, then started shooting at a truck that was moving through the facility, killing one of the Americans. Then he went inside the facility where people were having lunch and killed four more people before he was shot dead.

Lloyd “Carl” Fields, Jr., 46, of Cape Coral, Fla., formerly a deputy sheriff at Calcasieu Parish Sheriff’s Office in Louisiana, began working for contractor DynCorp International in 2006 as a police adviser in Iraq. He later worked in Afghanistan as a police adviser and embedded police mentor before moving on to Jordan. He left behind a wife and three children.

James "Damon" Creach, 42, of New Tampa, Fla., previously worked for the Virginia Beach Police Department and at the time of the attack worked as a law enforcement instructor for DECO Inc. He was married with three children.

A week after the attack, PJM was the first to report on ISIS' claim of responsibility issued in a statement through their Al-Battar Media Foundation.

"Yes... we kill the Americans in Amman," the terror group said, using the words "lone wolf" to describe the attack.

The claim was included in a chronological list of attack claims: the Russian Metrojet over the Sinai on Halloween, the Burj el-Barajneh bombings in the Beirut suburbs on Nov. 12, and the Nov. 13 Paris massacre. It was pasted on a file-sharing site and the link was disseminated among ISIS supporters on Twitter.

"Do not provoke the Muslims more than this, especially recruited and supporters of the Islamic State," the message said. "The more your aggression against the Muslims, the more our determination and revenge... time will turn thousands of supporters of the caliphate on Twitter and others to wolves."

ISIS also claimed the attack in an issue of their Dabiq magazine: "Anwar Abu Zeid – after repenting from his former occupation – attacked the American crusaders and their apostate allies, killing two American crusaders, two Jordanian apostates, and one South African crusader. These are the deeds of those upon the methodology of the revived Khilāfah. They will not let its enemies enjoy rest until enemy blood is spilled in revenge for the religion and the Ummah."

Jordanian and U.S. officials have never publicly attributed the attack to ISIS.
