PJ Media, by Patrick Poole, Feb. 26, 2015:

A man seen in multiple ISIS propaganda videos speaking with a British accent beheading Western hostages had his identity revealed in the Washington Post this morning, and yet again the suspect is another case of what I have termed “known wolf” syndrome since he was already known to authorities before engaging in acts of terrorism.
The Washington Post reports:

The world knows him as “Jihadi John,” the masked man with a British accent who has beheaded several hostages held by the Islamic State and who taunts audiences in videos circulated widely online.

But his real name, according to friends and others familiar with his case, is Mohammed Emwazi, a Briton from a well-to-do family who grew up in West London and graduated from college with a degree in computer programming. He is believed to have traveled to Syria around 2012 and to have later joined the Islamic State, the group whose barbarity he has come to symbolize.

But the article goes on to reveal that Emwazi had been detained by authorities not once, but twice:

Emwazi and two friends — a German convert to Islam named Omar and another man, Abu Talib — never made it on the trip. Once they landed in Dar es Salaam, in May 2009, they were detained by police and held overnight. It’s unclear whether the reason for the detention was made clear to the three, but they were eventually deported.

Emwazi flew to Amsterdam, where he claimed that an officer from MI5, Britain’s domestic security agency, accused him of trying to reach Somalia, where the militant group al-Shabab operates in the southern part of the country, according to e-mails that he sent to Qureshi and that were provided to The Post.

Emwazi denied the accusation and claimed that MI5 representatives had tried to recruit him […]

In June 2010, however, counterterrorism officials in Britain detained him again — this time fingerprinting him and searching his belongings. When he tried to fly back to Kuwait the next day, he was prevented from doing so.

The BBC added that Emwazi was part of a known network of jihadist sympathizers:

We don’t know when the British or the American security services worked out that the masked man in the killing videos was Londoner Mohammed Emwazi.

But we do know that he was a “person of interest” to MI5 going back to at least 2011 because he features in semi-secret court cases relating to extremism overseas and back in the UK.

Nobody in official security circles is going to comment on what they know and why they know it.

Emwazi has been previously described as a member of a network involving at least 13 men from London – and at least two of them were subjected to house arrest control orders or T-Pims. One absconded. The chances of Emwazi ever returning to the UK are vanishingly small.

So yet again, as we’ve seen in practically every recent terrorism case, the suspect was already known to authorities.

I’ve reported here at PJ Media on the long line of “Known Wolf” terror suspects who committed acts of terror:

Earlier this month I reported that Copenhagen shooter was Omar Abdel Hamid El-Hussein, who had been convicted in a stabbing in December, and yet remarkably released by authorities despite being branded as “extremely dangerous.”
Also this month I noted that Moussa Coulibaly, who stabbed three police officers outside a synagogue in Nice, France, had just days before been deported from Turkey for attempting to join ISIS.
The two Kouachi brothers behind the massacre on the Charlie Hebdo newspaper offices last month in Paris had been long known to law enforcement, with one of them already having been in prison on terror-related charges, and yet they had been removed from the radar by authorities just last summer because they were deemed no longer a threat. They were also on the no-fly lists of both the U.S. and the UK.
Man Haron Monis, aka Sheikh Haron, who in December took hostages at a chocolate shop in the heart of the commercial district in downtown Sydney, Australia, was not only known to law enforcement, but was out on bond on two separate cases and had previously been convicted of harassing the widows of Australian soldiers killed in Afghanistan. Authorities had been tipped off via their hotline to extremist statements Haron had been making on his website 48 hours before the attack.
I first noticed this “Known Wolf” trend back in October after two separate attacks in Canada by Martin “Ahmad” Rouleau and Michael Zehaf-Bibeau, both of whom reportedly had their passports stripped by Canadian authorities because they were deemed “high risk” to travel overseas to join ISIS.

Yesterday, an interview I had with Erick Stakelbeck aired where I discussed the “Known Wolf” terror phenomenon (the first 11 minutes of the program):

Needless to say, if the currently growing track record of Western authorities missing these “known wolf” suspects is any indication, the next terror case will undoubtedly be a subject already known to law enforcement and intelligence authorities, but sufficient action not taken to stop their terrorism.
