You are not permitted to engage in self help and assault someone you believe robbed you. There is no self defense indicated in this fact pattern. You should have called the police and let them handle it. You can be prosecuted for assault and possibly other crimes. If there is evidence that other party committed burglary, then it may be possible that they be prosecuted as well.
Both will be prosecuted and both will probably lose, but what if the robber wins and the victims lose?
R. Jason de Groot, Esq. We do not have an attorney-client relationship. I am not your lawyer. The statements I make do not constitute legal advice. Any statements made by me are based upon the limited facts you have presented, and under the premise that you will consult with a local attorney. This is not an attempt to solicit business. This disclaimer is in addition to any disclaimers that this website has made. I am only licensed in Florida. If you wish to contact the above attorney, see his profile at this website.
Victims are now the defendants. They are facing assault charges, burglary charges, and possibly more depending on the additional facts. Assaulting someone who robbed you first is not justification for retaliation.
