“like a prison”. Wrought iron gates enclose it, several security guards patrol it, and occasionally drug-sniffi ng dogs scour it. Such security and punishment are part of what has been called a discipline regime in public school
A lot of this would have to do the location and current events that may be happening with school. For example my aunt was a high school during the LA Riots she has told me stories of her going through metal detectors for a huge part of her time at school. But a lot of it has to do there drug wars during that time and perhaps that was one way of it to stop circulating them on campus !
