School uniforms

I'm research a topic and would like to generate a bunch of arguments for data collection.

Policy:
Students in public, K-12 schools must wear school uniforms.

Background:
- Uniforms are uniquely designed for each school. (Think Japan)
- Students must purchase their uniform from the school.
- Students must wear their uniforms on school campus at all times. (Strict)

Instructions:
1.) Please state whether you are for or against the policy by labeling PRO or CON in the title box. In rare cases, you may label NEU in the title box if you don't care about the policy.
2.) State clearly the support for your answer by introducing reasonable arguments. If you can, please provide statistical data and resource locations.

Rules:
- Think logically and be considerate for both sides of the debate before you answer.
- Please do not use answers such as School uniforms are dumb!, School uniforms do nothing to improve the school environment., or any other personal taste, absolute remarks along those lines.

Ill generate a few arguments so you can get an idea of how this will work. Don't let the confusing numbers prevent you from displaying your opinions.
