Yes, you should hire an attorney, and yes, this may be something you want to fight. I would want to see the police reports and get more information before knowing for sure. would contact an attorney as soon as possible so that witnesses can be interviewed before memories fade.
Nothing in this communication should be considered legal advice. Nor should this communication lead you to believe that an attorney-client relationship has been created. Only after thorough analysis of your case with you in my office can I provide effective legal advice on your specific issue.
