Dallas Police sent a senior delegation to Monterrey on 8 April for joint security training, the first cross-border policing arrangement in World Cup history. Monterrey's mayor and police chief had previously visited Dallas, completing a bilateral exchange.
The arrangement reflects the structural reality of a three-nation World Cup: fans will move between US and Mexican host cities during group stages, requiring coordination that no previous tournament has needed. Vancouver Police's confirmed exclusion of ICE from Canadian venues creates a contrast in host-country security postures. The arrangement is informal (a liaison visit, not a formal treaty) but it is the first of its kind for the tournament.
