Alexandre D applied for jobs in Rambouillet where he "demanded not to work with women". His passport included stamps from a host of countries.
Again this is part of a pattern. But the meaningful part of a pattern isn't that the attempted murderer was known to law enforcement, but how he was known.
Law enforcement in the UK and France keep tabs on Islamists. They have more freedom to do so than the FBI does. They also have more freedom to actually deal with the Islamist groups they are monitoring. Instead they let those groups continue to operate, they monitor and track them and then one of their spawn goes on a killing spree.
A 21-year-old arrested on suspicion of stabbing a French soldier in the neck in Paris was flagged up to French intelligence months ago over fears he has been radicalised, it has been claimed.
Alexandre D, as the French suspect has been called, was arrested in Yvelines, just west of Paris early on Wednesday morning at a friend's flat.
Police are seeking to determine whether the Paris attack might have been inspired by the Islamist murder of a British serviceman in London, although sources told Le Monde newspaper that French intelligence was recently warned the suspect, who converted to Islam around three years ago was "becoming increasingly radical".
The warning came in a note written by the police intelligence unit of the Yvelines area where Alexandre was arrested.
The note provides a fairly detailed account of the suspect's evolution towards a more radical form of Islam since 2009, pointing out that police had remarked he had "suspicious behaviour". Homeless and unemployed, Alexandre D applied for jobs in Rambouillet where he "demanded not to work with women". His passport included stamps from a host of countries.
The multiple countries suggests this fellow may have tried to hook up with an Al Qaeda group. And even if he didn't he was clearly on the radar. The authorities chose not to act, not just against him, but against the larger groups that promote terror and then avoid the consequences when one of their new converts goes for the kill.
