When you bring in the DOJ, if they decide to take your case, they will not be representing you. They represent Uncle Sam. Uncle Sam sues the county. If Uncle Sam wins, you will usually be issued a right to sue.
You will most definitely win if Uncle Sam does.
However, the waiting period can take up to two years. I would follow Reba's advice about writing to your Senator. I would also find out if there is a State Sponsored Disability Rights Advocacy Center and set up an appointment pronto.
