In his opinion, Policinski stated that instead of being successful at silencing anyone, these attempts at censorship and the Paris massacre have backfired and instead brought more awareness and support to freedom of speech.
"Ironically, such violence directed at journalists, authors and others is recognition that free expression and the marketplace of ideas—enshrined in the U.S. [Constitution] in the First Amendment—is a powerful weapon against tyranny", he wrote; "For more than 220 years, in the U.S., the 45 words of the First Amendment have defined the nation's core freedoms of religion, speech, press, assembly and petition.

[28] Glenn Greenwald accused supporters of Je Suis Charlie of either keeping silence about, or downright supporting, what he sees as free speech violations perpetrated by the French state in the year that followed the massacre, including the following events: the arrest of comedian Dieudonné M'bala M'bala for hate speech, and of further dozens of people for "acts insulting religious faiths, or for cheering the men who carried out the attacks"; the criminal conviction, by France's highest court, of pro-Palestinian protesters for having advocated a boycott of Israeli products at a supermarket; the shutting down of mosques and coffee shops; and France's use of "emergency powers", after the November 2015 Paris attacks, to ban a rally by environmental activists in protest to the 2015 United Nations Climate Change Conference which was taking place in the French capital.
He has accused most Je Suis Charlie supporters of being, not true advocates of free speech rights, but anti-Muslim agitators who used the massacre at the magazine's headquarters as a "cynical weapon".
[30] Todd claims that the marches on 11 January 2015 to show solidarity with the Charlie Hebdo victims were not an expression of positive French values but of right-wing and anti-immigrant elements in France.
