Social distancing and stay-at-home measures provided scientists with a natural experiment to study social phenomena that hinge precisely on human mobility and contact — including criminal activity. A study by Center for the U.S. and Mexico experts and co-authors explores the relationship between COVID-19 and criminal activity in Mexico.

Gun shows are public gatherings where licensed gun dealers and private gun owners use formal and informal venues to exchange information or sell and buy firearms, accessories, and ammunition.

This article makes the argument that the city's descent into violence and chaos is the result of a number of poor decisions made over the course of the 40 years preceding the bloodshed of the years under examination.

While Mexico, the U.S. and the Central American sending countries share responsibility for contributing to the recent surge, they also share the responsibility to find a solution.

Theory-building in border studies would go further if closer attention were paid to methods instead of the nature of borders and borderlands. Careful attention to methods would help make variables more amenable to theory building.
