When Parkland students returned to Marjory Stoneman Douglas High School after spring break, they were met with several new security measures designed to prevent another school shooting. However, as many students are pointing out, the new measures may be doing more harm than good.

One of the students’ main concerns is the new rule that only clear backpacks are allowed on campus.

Many students who were issued with the new “safety backpacks” are not happy. They say it is not only a violation of privacy but is also unlikely to prevent another tragedy.

On Monday, the superintendent of Broward County Public Schools, Robert Runcie, sent a letter to parents and students, which stated:

“When students return from spring break, clear backpacks are the only backpacks that will be permitted on campus. While we cannot change the heartbreaking and senseless act of violence at Marjory Stoneman Douglas, by working together, we can change the future.”

The backpacks are designed so that the contents are visible from the outside. The idea is that it would be much harder to hide a gun and bring it on campus, but there are three flaws with this idea.
