When I was in high school, a kid brought a gun to school and had it in his book bag until his friend told a teacher and they took the bag and called the police. After that you could only use see through book bags, and it was so convenient that the school started selling these right after so a lot of people bought them until they found out the school was charging more than Wal Mart. The bags were thin plastic so they always broke too, you cold use mesh bags but they had to be approved, basically if you could see everything in them, and those got caught on everything, and tore all the time too. It was stupid, if I wanted to bring something I could, clear book bag or not, all it did was piss people off.
