Baltimore's CBS affiliate, WJZ, released the video, originally captured by a student at Reach Partnership high school, and alerted the authorities. It shows an officer hitting a male high-school student in the face and trying to kick him as a second officer stands by.
Both cops, as well as the head of Baltimore school police, Marshall Goodwin, have been put on administrative leave. Neither the events preceding the scuffle nor whether the student attends Reach Partnership has been confirmed.
"I'm a parent, and I'm totally appalled at what I saw in that video. No matter what the circumstances are," said Karl Perry, who took over the School Supports Office — a department that tries to improve the climate for students — last June and has criticized the system's "soft code of conduct."
When Perry came into his position he vowed to "return to zero-tolerance enforcement of [his] expectations for appropriate behaviors."
The Baltimore Sun has frequently challenged the district's approach to policing, reporting that, according to the Department of Juvenile Services, school arrests account for 16 percent of juvenile arrests in Baltimore (versus one percent in the rest of the state).
