Alex says he loves video gaming and wants to play every day.

“I don’t want to sound like I’m a future serial killer, but it’s fun,” the 12-year-old says. “In the gaming world, like, you can get away with stuff. You can steal cars, you can kill people. You’re going at each other full force with guns blazing.”

“When somebody tries to mess with me when I get mad, I will punch, slap, hit, bite – I’ll do whatever I can to get you out of my way,” Alex says, adding that he has beat his door with a golf club to release his anger. “At home, I kind of have free range because everybody knows when I get that mad, you don’t come over to hit me, to punish me, to silence me, because I’ll hit you.”
