Last week, another American teenager killed several people in what police say may be an ISIS related domestic terror incident. It's clear we have a problem. We can wring our hands, or bury our heads in the sand. Or we can face this problem and take 5 simple steps to protect our children and stop the radicalization of young people in our homes and communities. I say we act, now, today, to make a difference, before other young lives are needlessly lost to tragedy. Who's with me?
