In the days after two American citizens were shot and killed in Minneapolis earlier this year, former Homeland Security Secretary Kristi Noem said the department would "rapidly acquire and deploy" body cameras to its officers around the country.

Nearly half a year later, after another shooting death under disputed circumstances blamed on the department, the promise still hasn't been fully met - prompting outrage from critics who say the cameras are a chance at accountability for officers enforcing President Donald Trump's immigration crackdown.

The Immigration and Customs Enforcement officers involved in the Houston shooting death of Lorenzo Salgado Araujo, a Mexican man who lived in the U.S. for more than 35 years, were not wearing body cameras, Homeland Security has said.
