Last week the French interior minister, Bernard Cazeneuve, announced the total so far of apartment searches (1233), detentions (165) and charges preferred (124) since the state of emergency came into force shortly after the killings on 13 November. Dividing the country’s ‘Muslim’ population by the number of detentions we arrive at a figure of one for every 30,000 or so: this is not an anti-Muslim witch hunt. Nonetheless the emergency has been extended for three months and yesterday the total of arrests leaped, with 200 or more after the COP21 demonstrations in Paris – a big, scheduled march having been banned under the emergency – turned rough.
