SB's swearing rises to the level of verbal abuse and threats, IMO. She wasn't just swearing out of frustration-- she was clearly verbally abusing, baiting/ antagonizing, and threatening the officer, IMO. And escalating the situation.
She should have exercised her "right to remain silent", or at a minimum, faked some polite behavior. IMO, she is responsible for escalating the situation, and causing her own arrest. It's not like she hadn't been arrested before-- with her history, she should have been an "expert" at acting socially appropriately, to get out of trouble.
I'm glad she was arrested before she hurt someone else. Her history of nearly $8000 in unpaid traffic fines, substance abuse, and multiple traffic violations-- along with her impulsive, argumentative, and combative behavior makes me really glad she was off the streets.
Be that as it may, it's very sad and unfortunate she chose to commit an impulsive suicide 3 days later. I can't fathom why so many want to blame her suicide on the arresting officer-- but no one is criticizing the family members who wouldn't bail her out, and only a few find fault with the jail personnel. A lot of people want to pile on the arresting officer, but ignore how her own behavior rapidly escalated the situation from a simple stop, to an arrest.
People who want to make every encounter confrontational and oppositional have a very hard time moving smoothly and successfully through life-- they have trouble with a lot of social interactions, can't hold jobs, can't follow rules or laws, defy and combat any forms of authority, and generally live within a lot of self-induced chaos. IMO. (And that's leaving out the considerable compounding effects of substance abuse and mental illness.) Police officers are faced with dealing with these kinds of deeply dysfunctional people 24/7-- and they don't get to make any mistakes, lose their temper, or have a bad day.
