They may be worlds apart in terms of distance and policy, but the police forces of Texas in the United States and Fulham and Hammersmith in London came together this week to exchange ideas.
Sergeant Phil Darnell is head of patrol at the Addison Police Department in the south-central American state, which has executed more people than anywhere else in the country.
The second biggest state in America, Texas dwarves H&F, which is one of the smallest boroughs in London.
Yet despite their differences, Sergeant Darrell and H&F's Chief Inspector Derek Barham believe they exchanged valuable information of mutual benefit.
Ch Insp Barham said: "This was a good opportunity to discuss current US policing practices, which have relevance on the streets of London, such as vehicle patrols and effective patrolling strategies.
"There were some clear similarities and common themes in how policing is delivered."
Sgt Darnell, a police veteran of 30 years, said: "My visit was a fascinating opportunity to see the Metropolitan Police at work and to discuss common policing issues and tactics with UK colleagues. I really appreciated the camaraderie extended to me by Hammersmith and Fulham police."
