It turns out that when correcting for poverty, crime rate, and the like, the only thing that determines the level of law enforcement personnel at a school is solely determined by the percentage of black students:

With the viral video of a police officer violently arresting a black female student at high school in South Carolina reinvigorating the debate over school resource officers, new research bolsters critics’ claims that school security can have a negative effect on students, particularly African Americans.

The new study by two academics in New York showed that the mere presence of African American students at a school makes it more likely the school will take on security measures, even when controlling for neighborhood crime and school misconduct.

The study also found, among other things, greater racial disparities in student suspensions and arrests in schools where there are cops present or other security measures are taken. Those arrest and suspensions are believed to contribute to the so-called “school-to-prison pipeline.”

This is not a surprise.

It has been “Zero Tolerance”, and “Getting Tough On insertnounhere”, etc. have almost always been primarily an a ploy to excuse racism.
