Each country has law governing what can and cannot legally be said or depicted about people in the media. According to this article, "The CSA, the government's media watchdog, warned to use "the greatest restraint" in broadcasting them because the French law on presumption of innocence does not allow suspects to be shown in handcuffs."
It isn't just US media taking pokes at French media. "The feminist French lawyer Gisèle Halimi, praised the US justice system, which she said protected women's dignity. "I am convinced that if this affair had taken place in France, we would never have heard anything about it," she told Le Parisien." (I'm assuming the Guardian produced the translation?)
This is a discussion that has to happen in every country, as each country weighs the risks of amplifying a false accusation vs. allowing people to continue abusing a position of power. It is an iterative process that tends to lag cultural consensus, IMO. I'm a big believer in making the powerful feel their position is precarious. I think it's good for them.
