App wont allow me to list all the charges together but they are serious charges anyway what can I legally do to help someones case when someone will testify against the defendent and I have known the witness for atleast 20 years but he is a known liar even more so when he is getting something out of it. I can testify to that fact along wifh some others anyway he is also now living with the victim who is ALSO THE DEFENDENTS WIFE so what can I do to make sure the Judge, the Prossecuting Attorney, and anyone that matters knows the witness should not be testifying at all???
