For the past 21 years, James has worked for a private security company as a plain-clothes officer in high-street stores, mainly on London’s Oxford Street. He’ll often film the people he detains, either to show to the police or to share with his colleagues over WhatsApp. But since February, he’s found a new home for his footage: his TikTok account, @london_content, which already boasts nearly 100,000 followers.
