The 225 students at Pennridge High School in Pennsylvania who joined the national walkout on March 14 were told to sit detention on a Saturday. The first group of 46 did. They sat on the floor, arms linked, with names of the 17 victims at MSD in Parkland, Florida, inscribed on placards.

There is a video on Twitter of their protest. 

These kids are great! They will be voters soon. Can’t wait!
