How does Charlie Kirk’s assassination spotlight the void in U.S. domestic-terrorism law (defined at 18 U.S.C. § 2331(5) but no standalone crime) and, per DHS/GAO data from 2010–2021, what patterns in motives, weapons, and targets — alongside a 357% surge in FBI cases — should policymakers confront?
The assassination of Charlie Kirk highlights the broader issues, not of faith but, of the domestic terrorism within the United States. Kirk’s murder should not have happened for expression of views, for demeanour, for beliefs, or stature in American society.
U.S. law does define “domestic terrorism” (18 U.S.C. § 2331(5)). However, no federal crime with this title exists as a standalone. Agencies track incidents using agency systems. They investigate using internal systems, too. Therefore, gaps will exist, because no mandatory local reporting to the FBI. FBI and DHS use different datasets.
DHS incident tracker counted 231 domestic terrorism incidents with known offenders between 2010 and 2021. 145 deaths were in the period, peaking in 2015 and 2019. 80 were racially or ethnically motivated violent extremists, 73 were anti-government or anti-authority violent extremists, 53 were mixed or personalized messages, and 15 were animal rights or environmental extremism. Therefore, racially motivated events were the most prominent of the categories.
Firearms were implicated in 92 incidents and responsible for 132 of 145 deaths. IEDs were used in 38 incidents with few or no deaths implicated. Therefore, armed assault is the workhorse with 98 incidents and 139 deaths while arson is 45 incidents with rare deaths.
Most attacks or plots were against specific civilians. Law enforcement was the second most targeted group. California had the most incidents. Several states recorded none in the aforementioned time period.
DHS’s Homeland Threat Assessment 2025 explains incidents from U.S.-based violent extremists remain high. These are largely driven by lone offenders and small cells. Those animated by racial motives, as well as anti-government, gender-related, and mixed motives. Many geopolitical events, e.g., elections of the Middle East conflicts, catalyze these events, too.
FBI open domestic terrorism cases, the investigative workload and not the incidents, between 2013 and 2021 increased by 357%. Baseline concern has increased, in other words.
