Nidal Malik Hasan, the perpetrator of the Fort Hood shooting that killed 13 people in 2009, is set to be executed by firing squad following approval from former President Trump. This marks the first military execution by firing squad in the United States since World War II. The Pentagon confirmed that Hasan, who was an Army psychiatrist during the attack, will face execution nearly 17 years after the massacre at the Texas military base. The decision to use a firing squad has garnered attention as it is the first military death penalty case approved since 1961.
