Yes she was. Because she refused to get out of her vehicle.

She was only asked to get out of the vehicle because she was self-admittedly "agitated" and began increasingly berating the officer in a way that was keeping him from finishing writing the citation.

So again, if an officer asks you to get out a vehicle, comply and ask if you're being detained. Don't grab your phone, don't tell the officer he doesn't have a reason to ask you to get out of the vehicle, after just admitting that you're agitated.
