DHS Official Killed: Alleged Vetting Failure Exposed

A U.S. Department of Homeland Security (DHS) official was killed by a naturalized citizen, according to agency statements. The incident has exposed what experts call a major breakdown in immigration security checks. Lauren Bullis, a DHS employee, was recently killed. The person accused of the crime is a naturalized U.S. citizen. Internal reviews and outside policy experts point to serious failures in the vetting process. Vetting is the system of background checks for people applying for U.S. citizenship. These checks are designed to screen for security risks. The DHS said the loss has left the agency "devastated." The case is forcing a direct examination of how a person who passed through the immigration system could later be accused of such a crime against a DHS official.
