Didarul Islam, a 36-year-old off-duty New York Police Department officer and Bangladeshi immigrant, was killed while attempting to stop a shooting inside a Manhattan skyscraper. Islam had served with the NYPD for four years and was a father of two sons, with his wife eight months pregnant with their third child. The shooting, the deadliest in New York City in the past 25 years, has intensified public safety concerns and become a focal point in the New York mayoral race. Mayoral candidate Zohran Mamdani honored Islam and called for stricter national gun laws, including a nationwide ban on assault rifles, during a press conference. Mamdani's stance on gun control has highlighted potential vulnerabilities in his campaign amid heightened public safety debates.
