Hero wrestles gun from terrorist at Bondi Beach

It's been a terrible week for gun violence, both here and around the world. Early Sunday, two shooters opened fire at Australia's Bondi Beach, killing 15 people. Most people run from danger — understandably. Plenty of armchair commandos and tactical wannabes love to theorize about how they'd stop a violent incident with their concealed carry and weekend warrior training. But at Bondi Beach, the man who ran toward danger to protect his family and bystanders wasn't a good guy with a gun. He had no body armor and probably didn't think twice about the implications.

Ahmed al Ahmed, a 43-year-old enjoying the summer sun, came up behind one of the gunmen and wrestled away his shotgun. Look at him. He's not built like an action hero. That T-shirt probably came in a five-pack. Ahmed is just some guy. While seizing the weapon from the terrorist shooting up the beach, Ahmed was shot twice—a price paid for saving countless lives.

Don't think you can't change the world because you're only one person. Your kindness and bravery can alter the course of history.
