The Kouachi brothers called each other non-stop - over a thousand calls from January 2014 to January 7, 2015 - but were wary of cellphones.
Amedy Coulibaly had, from September 2014 to January 2015, 17 mobile lines.
But, in the days preceding his carnage, he only used two, specially opened in order to join a limited number of acquaintances, many of whom are in the box of the assizes of Paris.

Trial of the January 2015 attacks: how the prosecution prepared
What a pity that these observations, of which a policewoman gives a summary at the trial of the 2015 attacks, could only be made posthumously, after the violent death of the three Islamist terrorists.
It appears that, unlike Chérif Kouachi, domiciled in Gennevilliers, and his brother Saïd, who lived in Reims, the Hyper Cacher killer was on the move.
The "boundaries" make it possible to follow him to Paris, in the suburbs, as far as Spain - country through which his wife, Hayat Boumeddiene, leaves Europe in the direction of Syria, a week before her husband takes action .
From January 1 to 7, 2015, the latter does not hold in place.
He maintains intense SMS exchanges with a handful of relatives, whom he also meets a lot.
Their names: Amar Ramdani, Willy Prévost, Ali Riza Polat and Nezar Mickaël Pastor-Alwatik.
The contacts correspond to data in the file: purchase of weapons, trafficking in the car used by the jihadist to get to the Hyper Cacher, and a motorcycle that he had probably planned to borrow to escape. de Montrouge, January 8, after a probable abortive attack on a Jewish school.
On that fateful day, however, he murdered the young municipal policewoman Clarissa Jean-Philippe.
The four men look at their shoes, embarrassed by this proximity to Amedy Coulibaly.

Only Mr. Polat, true to himself, grumbles in the box, but as his microphone is not open, we do not hear what he objected vehemently.
If demonstrating the existence of this gang is within the reach of a 4-year-old child, the question arises of the knowledge, by the accused, of the nature of the crimes that Coulibaly alone was going to perpetrate.
Mr. Polat responds with complicity, but the others with a terrorist association: the prosecution has failed to "hook" them further.
