The Parkland students had a few thoughts on their new clear backpacks

"You know, I feel super safe now that the whole school can see my collection of tampons and pens."

The students of the school in Florida which was targetted by a gunman in February returned from spring break on Monday to a wave of new security measures, including mandatory clear backpacks for all students.

17-people were killed at Marjory Stoneman Douglas High School when former student Nikolas Cruz opened fire.
