The new measures were put into place after the Valentine's Day mass shooting, in which 17 people were killed, and few recent security breaches at the school. Student Josh Gallagher said, "This clear backpack idea is to give us kids a false sense of security and now has enraged most of the students here at MSD".
Others pointed out it was an invasion of privacy, particularly for young girls who needed to carry pads and tampons, or for students who require medication.
Students and faculty also must now wear identification badges at all times. Eight highway patrol troopers were added after a student brought a knife to school, another made online threats and the brother of suspected shooter Nikolas Cruz was found skateboarding on campus.
"We come to school to learn, so I don't think that we should need to subject ourselves to these measures".
"If we are going to have more police officers at school, that only makes the problem worse".
"We wanted to have an outlet", said Lorena.
"I thought her comments were well placed to a guy who had gone off the rails. spewing the hate", Nugent said.
The school will provide them to the students free of charge.
Another student tweeted a photo of her clear backpack that had nothing but a handwritten note inside which read: 'This bag contains everything politicians care about, besides money'.
"For those of us who were there, we saw things and heard things". The tags were also seen during last month's March for Our Lives in Washington, D.C., when student activists David Hogg and Lauren Hogg said the dollar amount represented how much Republican senator Marco Rubio accepted from the NRA divided by every student in the state.
The shooting galvanized a student-led movement calling for stricter gun laws, and some students used the clear bags to make a political statement. A letter from Principal Ty Thompson sent to families on Friday said that step has not been taken yet.
The school district said it's considering whether to install metal detectors at the school's entrances. Sports bags and instrument cases are now checked at entry points and must be dropped off with a teacher or coach before school starts.
