Reducing crime is not complicated. Governments must make crime riskier by increasing arrests and convictions, imposing longer prison sentences, and allowing law-abiding citizens to defend themselves. The news on each of those fronts has been encouraging.
FBI arrests surged in 2025, rising 184 percent over 2024 levels. Total FBI arrests — a broader category that includes many joint operations with state and local agencies — increased by 197 percent.
Voters also replaced several George Soros-backed prosecutors in jurisdictions such as Los Angeles and San Francisco with district attorneys who prosecute criminals more aggressively and seek tougher sentences. Across the country, President Trump’s U.S. attorneys have also pursued criminals far more aggressively than their predecessors. In Washington, D.C., for example, the Biden administration’s U.S. Attorney declined to prosecute 67 percent of those arrested. Under U.S. Attorney Jeanine Pirro, that figure has fallen to just 4 percent.
Nor is it a coincidence that the record influx of illegal immigrants during the Biden administration coincided with a sharp increase in violent crime. It is equally unsurprising that crime has fallen as deportations have increased. Deportation records show that 70 percent of illegal immigrants deported during the Trump administration had either criminal convictions or pending criminal charges in the United States. Even those who avoid arrest understand that any contact with law enforcement could lead to deportation, giving them a strong incentive to stay off the police’s radar and avoid committing additional crimes.
Finally, the number of adults carrying concealed handguns has risen sharply, with the latest survey data showing a 5-percentage-point increase in concealed carry over the past year and a half.
