Samuel you really should try to counter this argument however I understand it will be hard to do. But honestly when you look at black crime rates for over 35 it's significantly lower than teenage to 30 rate. So perhaps focus in 🏫 is justified.
The data shows black kids are arrested at school almost exclusively for disorderly conduct and fist fights. It isn't about criminality it's youth getting arrested for youthful behavior that previously would've been handled with detention/suspension.
And if you look at the study it actually shows white students are more likely to be involved in/arrested for more serious offenses, though again these offenses made up only 9% of school arrests. So if there's allegations of criminality, it makes more sense to direct them there.
Our school resource officer is an integral member of the school. The officer talks with students, and develops relationships with those students. I don't know statistics but would say that very few if any students are actually placed under arrest. I will have to find this out.
