The Chief Constable of Avon and Somerset Police says he was 'horrified and concerned' at video footage showing George Floyd's treatment by police in the US.
Andy Marsh has released a statement as many groups, including ourselves, today pause social media posts as part of the #BlackOutTuesday campaign.
He said: "I would imagine like every other serving officer in the USA and across the world, I felt horror and concern at the video footage showing the senseless and tragic killing of George Floyd in Minneapolis at the hands of a police officer, who’s since been dismissed from his post and charged with murder.
"Silence in the face of injustice incriminates us all. I do feel ashamed to have the same occupation as an individual that behaved like that and I’m concerned at the damage this will do to the work we’ve been doing to build trust, confidence and better representation within the communities we’re here to serve, protect and respect.
"It’s important to stand up for fairness, equality and inclusion. Social responsibility is a shared response and we all need to play our part. Now is not the time for just more fine words, condemnation and calls for change.
"We in Avon and Somerset Police, along with our communities and partners, are redoubling the important and meaningful work already in hand to contribute to a stronger, fairer society built on a foundation of equality for all."
