Quick Google says that no one in that school was suspended for their participation or lack thereof in the walkout.

He was suspended for not going to the study hall where non-participants were supposed to gather. School policy is to not leave students unattended, for security reasons.

Yet another intellectually lazy person who thinks remaining “apolitical” somehow makes him better. Being “apolitical” is a vote for the status quo. This guy is perfectly fine with his peers getting gunned down.
