Why School Dress Code Is Important [VIDEO] General by Joel Wagner - June 18, 2007July 5, 20101 How many guns do you see? This is an amazing video that demonstrates the violence that can result simply by a school’s failure to have an enforce a no-tolerance dress code. I have watched this video numerous times to check and recheck how harmless he looks at the beginning of the video. Truly amazing and frightening at the same time. Joel WagnerJoel Wagner (@sywtt) began teaching band in 2002. Though he had a lot of information, his classes were out of control. He found himself tired, frustrated, disrespected by students, lonely, and on the brink of quitting. He had had enough. He resigned from his school district right before spring break of his second year and made it his personal mission to learn to be a great teacher. So You Want To Teach? is the ongoing story of that quest for educational excellence.
