Was this the extreme in domestic violence?

Man and woman had been married for several years. one cheated on the other and a divorce ensued. while waiting for a divorce court date, the woman wanted to protect “her property” from being taken out of their house, by her husband. woman hires a security guard to protect her bedroom. man has property in this bedroom and attempts to recover it. security guard pulls his weapon and fires at husband. security guard arrested for felonious assault. was this carrying domestic violence too far? if so, how? and, how should each persons personal property have been protected from theft by the other party?
