Border Patrol agents we spoke to aren’t sure how a border wall will change the dynamics between law enforcement and people trying to evade them. But drug tunnels, patches to the border fence and rings of concertina wire serve as reminders that for every measure taken to fortify the border, there have always been countermeasure to get around them.

Though plans for a border wall – a literal barricade dividing the U.S. and Mexico – are moving forward, the vision for a property just south of the existing border fence strives to connect Tijuana and San Diego more than ever by becoming a hub for where people from both sides of the border can live and work.

Both Tijuana Mayor Juan Manuel Gastélum and San Diego Mayor Kevin Faulconer have made public statements on the importance of strong ties between our cities and nations. But neither has taken a strong stance against the actual policies causing the economy and security of both cities to crack and fray.

Immigration to the U.S. from Mexico might soon slow even without a wall, but companies are clamoring to build one anyway. Plus: More violence in Tijuana, ongoing fallout over the sewage spill, journeying to the U.S. in video game form and more in our biweekly roundup of news from the border.
