Suspected Florida Gunman Remains Silent In Court
A Florida judge entered a not-guilty plea for Nikolas Cruz.
Cruz faces a possible death penalty for the massacre at a Parkland, FL high school.
The shooting last month killed 17 people.
It also triggered a national debate on gun control.
19-year-old Cruz remained silent during a hearing in Broward County circuit court.
Cruz’s court appearance coincided with a day of national student walkouts.
Thousands of students poured out of classrooms to protest against gun violence.
