My research at the Cato Institute on crime and terrorism committed by illegal immigrants conclusively shows that they commit less crime than native-born Americans and have murdered zero people in domestic attacks since 1975.

Southport Attack: Changing the Definition of Terrorism Won’t Stop the Violence
Axel Rudakubana, who killed of three young girls in Southport in a stabbing attack in 2024, had been referred to the Prevent counter-terrorism program three times, but failed to meet the threshold for intervention. Some want to change terror laws to deal with lone, violent killers. But as a researcher of counter-terrorism laws, I argue there is little point to widening what is already a broad definition of terrorism.

Autonomous Weapon Systems: No Human-in-the-Loop Required, and Other Myths Dispelled

Among these truths: “Not all lawful exercises of authority are wise, prudent, or smart”; “Not all crimes require a federal response”; “Avoiding tragic and unnecessary confrontations is generally desirable”; and “It is thus unwise, imprudent, and stupid to take actions for performative reasons that one might reasonably anticipate would increase the risks of such confrontations.”
