Belligerent behavior is not a definition of a crime. However, her conduct could be considered "disorderly conduct
" which is punishable in Florida by up to a $500 Fine and/or up to 60 days in jail
It could also be defined as Disobeying a Police Officer's Lawful Orders, which could result in a maximum of a $1000 Fine and/or up to 1 year in jail.
It is quite possible that the police could simply choose to drop the charges. If they do charge her with something, it makes a difference which offense is charged. If this does go to trial
and this is a first offense, it would usually result in a few hundred dollar fine or community service. Jail time would be unlikely, though it is an option for the court.
If the police decide to file charges, they will notify her of this fact. At that point, your best bet is to have an attorney negotiate with the prosecutor's office. You may get lucky and have the charges dropped, or agree to a negotiated plea deal of a small fine or community service.
I hope this helps!
