This took place 1st June 2013 in Frankfurt (Main) as a peaceful demonstration against German and European austerity policy. The police forced the protesters to leave the judical approved and carefully planned route. In the aftermath several hundred protesters got intentionally locked-in by them. Protesters were treated with tear gas or held in custody. I couldn't get to the heart of it due to the lock-in but and tried instead to convey the atmosphere and what are the driving reasons of the protesters.
