No, it is more likely that the paperwork never left the police desk as you where compensated for your hospital bills.
I doubt he ever admitted to a murder attempt, have you seen the paperwork of him doing so? Not very likely as you don't want to use a lawyer.
Now you are making up things that he could get you killed.
Instead of complaining on a forum, you should first use all the legal things available to you to get him convicted. The first part of that is get a good lawyer involved.
