Nadya Tolokonnikova tells the Guardian she felt she had ‘entered a wormhole’ when her police state exhibition was shut down – by the police state

Nadya Tolokonnikova, the co-founder of the feminist art collective Pussy Riot, was sitting in a replica Russian prison cell in downtown Los Angeles when the police started shutting down the streets around the art museum.

Police helicopters hovered overhead. Somewhere, through a loudspeaker, an officer delivered a tinny order to disperse.
