Nickolas Wilt, a 26-year-old officer who had graduated from the Louisville Metro Police Department Police Academy just 10 days prior, was critically injured while trying to stop a bank shooter on Monday. Wilt was one of three officers injured while responding to the mass shooting that occurred in a downtown Louisville bank, resulting in four deaths and multiple injuries. The shooter, a former employee of the Old National Bank, live-streamed the attack and used an AR-15-style rifle as the weapon of choice. Local officials praised Wilt as a hero for running towards the gunfire to try to save lives. He underwent brain surgery, and as of Monday afternoon, was in critical but stable condition. The gun used in the massacre is the most popular sporting rifle in the US, with 30% of gun owners reporting ownership of an AR-15 or similar-style rifle. Although the incident has shocked many, discussions about gun control in Kentucky are still considered an "uphill battle."
