A fatal shooting involving federal immigration officers during a traffic stop in Houston has increased scrutiny of Immigration and Customs Enforcement operations. Survivors and witnesses dispute the official suggestion that officers were in immediate danger, while the federal agents involved were reportedly not wearing body cameras. The man who was killed was a Mexican national and was not believed to have been the original target of the operation. Lawmakers, lawyers and civil-rights organisations are calling for an independent investigation and wider use of body cameras. The case comes during a broader national debate over immigration enforcement, transparency and the use of force.
