The Louisiana earlier this month voted to allow students to wear bulletproof backpacks on campus and at school-sanctioned activities.

The bill is written as an exemption to state law that bans the wearing of body armor by students. Bulletproof backpacks can be sold either as a complete backpack or as an insert that can fit into an existing backpack.
