During this election season, the topic of “border security” has become front and center in US politics. This video by AJ+ helps explain what’s actually happening at the border, and whether building a wall can actually help.

The video exposes some uncomfortable truths about how border security works. For example, though we often complain about violence in the area, there are three gun dealers per every mile of the US side of the border. And though we often portray the border as an uncontrolled area, between 2014 and 2015, border agents have actually more than doubled, while illegal immigration has actually decreased.

The video presents the question: at what point is border patrol “security” and what point is it “militarization?” Watch above to learn more.
