Oops is, yet again, a police term

Josh Voohees has a Slate article about excessive force:

"We've been training for this event for several months now," Tucson, Arizona police Sergeant Pete Dugan said in praise of his department's handling of the large, unruly crowd that gathered downtown the previous night following the University of Arizona men's basketball team's overtime loss in the NCAA tournament. "It got a little rowdy and it got a little violent, but no businesses suffered any damage."
It's unclear which category, "rowdy or violent", Dugan would label the blind-side body check leveled upon an unsuspecting woman by one of his department's riot gear-clad police officers (video, above).
Tuscon police say the video, which was published by the Arizona Daily Star over the weekend, is currently being reviewed by the department's internal affairs division. To be fair, it's a relatively short clip without a whole lot of context. Regardless, it's mighty difficult to construct a narrative that required the police officer to respond with that degree of force. Here's how Phoebe Landolt, the person who shot the video, summed things up in an interview with the local paper: "These girls had been trying to get to their car. The girl is on her phone not paying attention and this cop came out of nowhere and just leveled her," Landolt said. "After that everyone just started yelling and she started crying."
Police arrested a total of fifteen people, nine of whom were students, during the night, which saw fans reportedly hurl beer bottles and firecrackers at officers. Officers responded with pepper spray and pepper balls, more than a few of which hit this guy, Alexander Davidson, who was among those taken into custody:

Rico says ya gotta be stoned to take a half-dozen pepper balls in the chest and keep smiling while the police tackle you (see the video here)...
