Even allowing for the ubiquity of cameras and their tendency to dramatise events that maybe went unseen in the past, these scenes were disturbing.
Among the Paris commentariat, there is general agreement. "The uncontrolled excesses sum up better than any speech the social blockage which afflicts the country," said Le Figaro.
Financial daily Les Echos said: "A few hundred hotheads have broken a symbolic barrier: the one separating a modern society where conflicts are settled through dialogue, and a culture where what counts is brute force."
But the truth is that mob violence is far from a new phenomenon in France.
The question is whether today's conditions are making it worse.
Recent years have seen regular reports of workers "kidnapping" bosses in order to exert pressure during negotiations.
In 2014, for example, it was two managers at Goodyear in Amiens who were"bossnapped" for more than a day, after the plant was threatened with closure.
Sometimes the workers have trashed management offices; sometimes - especially when a factory is being shut - they have gone further and smashed machinery.
One practice - documented at a factory in Auxerre - was to force the manager to take part in a demonstration against his own policies: a kind of humiliating symbolic confession.

If some of this is redolent of the French Revolution - with its jeering abuse of the class enemy - then that is no coincidence.
French political and social culture is still strongly under the influence of 1789-93, though of course with an admixture since of conservative counter-currents.
Memories of the Revolution have been relived at regular intervals: the uprisings of 1830, 1848, the Paris Commune of 1871; the bitter divisions over church and state at the start of the 20th Century; the undeclared civil war in World War Two; thes treet clashes of May 1968.
In a way that would surprise people in the UK - where a free-market culture has taken root over the past 25 years and business leaders are heroes - in France the language of class war is still very much alive.
In some companies, union notice-boards carry posters that can be quite alarming to the unprepared: cartoon caricatures of bosses - fur coats, cigars, dollar bills tumbling from waistcoat pockets - not much different from what would have been on display in the 1930s.
Strikes and protests are universally described in the media as being conducted by such-and-such a group of workers "en colere [angry]" - the description implicitly conceding the justice of their cause.
But if workers' protests have long been part of the French way of life (the first bossnapping was more than 100 years ago), can it be argued that they are getting worse?
The answer is yes.
One reason is the general social climate in France.
Today, the French talk of "economic crisis" as a fact of life. There is mass unemployment, and people live on very low incomes.
Politics changes nothing, so the mood favours dissent.
Secondly, there is the effect of social media, which exaggerates grievances and whips individuals into states of righteous hatred.
And thirdly - and linked to these - is the sidelining of the official union representation.
Unions - paradoxically - are weak in France, in the sense that membership levels are low.
They are strong only in the sense that the law accords them a central place in the running of workers' lives.
They are thus part of the "system" - and the system is one that many working people feel has failed them.
So these people take direct action, outside of official union channels.
And unions - desperate to catch up with la base (the grassroots) - find themselves justifying behaviour they would otherwise have condemned.
This is what happened at Air France.
After the attack, one member of the CGT union said the violence suited management because it distracted attention from the real issues.
Worker-manager tensions are nothing new, and one should never forget that countries all over the world - not least the US - have seen outbreaks in the past of workplace violence and repression.
If the outside world is shocked by the Air France incident, some would say it is because the rest of the world has found new ways of dealing with labour conflict.
Others might say the rest of the world is docile: at least in France workers still fight the fight.
