NFL HQ Shooting Renews Concerns Over CTE, Guns

Shane Devon Tamura, a 27-year-old Las Vegas casino worker and former high school football player, killed four people, including a police officer, at a Midtown Manhattan office building housing the NFL’s headquarters before dying by suicide. Tamura left a note blaming chronic traumatic encephalopathy (CTE) and accusing the NFL of concealing football-related brain injury risks. Experts caution that CTE can only be diagnosed after death and is rarely found in amateur athletes. Despite a history of mental illness and two involuntary psychiatric holds, Tamura legally bought his firearm in Nevada, raising questions about gaps in gun control laws. Authorities are investigating both Tamura's claims and possible ties to law enforcement through his father. The attack has renewed debates about sports safety, mental health, and gun violence.
