Resolved: The United States federal government should substantially expand its surveillance infrastructure along its southern border.

The smart-border bargain

Pro’s pitch is deliberately moderate: surveillance is the humane, effective option in a debate stuck between walls and nothing. Towers, ground sensors, aerostats and AI-assisted monitoring extend agents’ view across remote terrain, intercept fentanyl and trafficking at scale, and give asylum processing earlier warning of who is arriving. It polls as common ground because it promises control without cruelty. Con’s job is to break that framing by showing what the bargain costs.

Deflection versus deterrence

Con’s lead empirical argument is the deflection effect. Decades of enforcement buildups didn’t stop crossings; they rerouted them into deserts and rivers where more migrants die. Surveillance towers push crossings into the gaps, which is the harshest terrain, so deaths rise even as apprehension numbers look better. Pro has two answers. It can pair detection with rescue capacity, since surveillance also finds people who are stranded, and it can contest causality: the deflection evidence comes from wall-era policies, and detection-first infrastructure works through a different mechanism.

Mission creep

The second Con argument is scope: border technology doesn’t stay at the border. Databases get integrated, drones get repurposed, and the hundred-mile "border zone" already covers most of the American population, so infrastructure built for migrants becomes the architecture of domestic surveillance. Pro’s response is institutional. Oversight, retention limits and statutory firewalls belong in any "substantial expansion" worth defending. Judges tend to score this clash on whose picture of bureaucratic behavior is more realistic.
