Among the post-riot measures to be enacted in Britain, Reuters reports, will be controls on face coverings and the possible use of the army to suppress future disturbances.

Britain will crack down on gangs and may call in army support if this week's riots are repeated, Prime Minister David Cameron said on Thursday, saying he would not allow a "culture of fear" to exist on the streets. The government will also give the police powers to demand people remove face coverings after many looters who ransacked shops during riots in London and other English cities this week wore masks to avoid being identified.

For what criminal activities (such as looting) is the appropriate response to demand someone remove a mask, instead of being arresting for the crime?
