From the bathroom, a loud bang jolted the hallway, witnesses would tell police. A burning sensation crawling up his left arm, ears screaming, [Mark J.] Bird popped out of the door, blood gushing from his left forearm, he said later. Bystanders flocked to his side. The smell of gunpowder drifted on the air. Someone tried to stop the bleeding with paper towels from a nearby maintenance cart. The panic button was punched. Medics and police arrived.

The pain did not muzzle Bird. In fact, the words spilling from the professor had a pointed political edge. As one witness told investigators, Bird "started saying he's protesting [President] Trump and that he shot himself because of that."

Bird's anti-Trump rhetoric would continue in his interviews with investigators. Although the professor survived his injury, he is now currently facing criminal charges stemming from the shooting, including felony counts of carrying a concealed weapon without a permit and discharging a gun in a prohibited area. Court records indicate he has yet to enter a plea.

A "less significant" factor in his decision was the Oct. 1 2017 mass shooting in Las Vegas, Bird wrote. "Since this incident, there has been no national legislation banning bump stocks, banning civilian ownership of AR-15 type assault weapons, and the passage of universal gun background checks legislation. Apparently, it is about as easy to buy an AR-15 as a 2-shot derringer."
