I'm an attorney (hopefully that's not an automatic ban ) and agree you "may" have a case depending on the circumstances. Hopefully she admitted to the police (in the report itself) that she kicked you... otherwise she'll flatly deny it. She may be able argue some form of self defense if she honestly thought you were the attacker (or his accomplice), but that's ultimately a question of fact.
Usually, I would just classify this type of event as an innocent freak incident, but given that she was so unremorceful (i.e. a complete b***) about it, I say consult with an attorney (sorry, I don't do litigation).
Die :twisted:
