Paris Mayor Anne Hidalgo, Prime Minister Jean Castex and other politicians were available to protest.
A special needs teacher working in the Paris area told CNN that she joined the demonstration because she was shocked by the murder.
“We all have to live together and learn to live together and everyone has to respect everyone’s faith,” she said.
The killer took a loan, the prosecutor said

Patty had taught a class on freedom of expression, during which he used caricatures of the prophet taken by Charlie Hebdo, causing controversy in the weeks before his death, authorities said.
Abuezidovic turned to students outside the school in the Paris suburb of Conflans-Saint-Honorine, asking them to point out Patty before attacking the teacher on the way home, Ricard said.
Abuezidovic, who was not known to intelligence, lived in Evreux, more than an hour away by car from the scene of the attack, the prosecutor said. It was not clear whether Abuezidovic attended the Collège du Bois d’Aulne.
Patty had organized a lesson on Charlie Hebdo’s cartoons, Ricard said. Nordin Chawadi, a parent of one of the students at the school, told AFP that Patti had taken steps not to offend Muslim youth in her class.
“It was just to keep them. It was out of pure kindness, because he had to show a caricature of the Prophet of Islam and just said to the Muslim children, ‘Come out, I don’t want this to hurt your feelings.’ “That’s what my son told me,” he said.
Several people were taken into custody
After a Danish newspaper controversially published the cartoons in 2005, Charlie Hebdo published them the following year.
On October 7, the father of one of Patty’s students called for Patty’s dismissal on Facebook. He also filed a complaint and posted a video on YouTube criticizing the teacher. Patty responded with a defamation complaint, Ricard said.
Police detained 11 people for questioning. Included are the father who complained about Patti and the daughter-in-law of the man suspected of “joining the Organization of Islamic State in Syria in 2014 and as such is subject to a search warrant by a counter-terrorism investigation judge,” said the prosecutor.
Abuezidovic’s parents, grandfather and brother were also taken for questioning, a French court source said.
French Education Minister Jean-Michel Blanker said Patti had been killed “for teaching a class linked to one of the pillars of democracy – freedom of expression”.
“Samuel Patti embodied the most noble value of our republic: its schools. He was cowardly killed by the enemies of freedom. We will be united, firm and determined,” Blanker wrote in a tweet.
Macron said Patty was “killed because she taught students freedom of speech, freedom to believe and not to believe.”
