"US police" ??? Contrary to weird headline, this was Adams County Sheriff's Office, and I know that fact because the Afroman video is still on Heavy Rotation for me.
Adams County is in the US, and I don't see much wrong with referring to a sheriff's office as "police". Of course, I don't know what audience the headline writer had in mind. "Ohio" might suggest a state agency, and "Adams County" would lead to confusion, since there are several.
I'd expect a better written headline to use "Adams County, Ohio Sheriff" since that is the most accurate form that conveys what agency did the thing in question.
