"Officer tackles 2 teen girls to ground over video recording"
https://abcnews.go.com/US/north-carolina-police-officer-investigation-slamming-teen-sisters/story?id=59766723So it appears like the officers pulled over a car for a legal reason and an arrest was made for the possession of an illegal substance. So far sounds completely correct in my opinion. As for the video taping the officer felt they needed to take possession of the video recording devices (in this case multiable cell phones). The officer called the phones "evidence" which isn't technically wrong.
A North Carolina sheriff's deputy was placed on leave after a video emerged of him slamming two teenage girls to the ground.
The Harnett County Sheriff’s Office said it placed the officer on administrative leave on Tuesday, a day after video surfaced on Facebook showing the girls being wrestled to the ground during an arrest, according to Durham ABC affiliate WTVD.
The sheriff’s office did not name the officers involved, but said the North Carolina State Bureau of Investigation has been called in to investigate the case.
The issue I find odd is why was the office placed on leave only after it went public. If it wasn't legal why wasn't it done right away?
The disturbing part is people being arrested just for filming:
The 17-year-old said she began recording because the officer tried to arrest her 14-year-old sister for filming the encounter. It is legal to film police officers in North Carolina, as long as it's a public space and you are not interfering with police work.
"Yo! What are you doing right now, she didn't do anything," the older teen is heard saying in the video as an officer grabbed her sister by the neck and wrestled her to the ground. "Why are you doing that? What did she do?"
At least that's how it seems. ABC sites

I wasn't able to find a record for use of force for this department (at this time) so I can't see if this was a pattern of aggressive behavior but for the most part it seems like a legal arrest followed by illegal arrests.
