Or maybe, Man Bites Dog . . .?
Don't know where you're coming from, but:
1. People don't get charged for the purpose of forcing them to testify against someone. There really does have to be a basis in fact and law for the charges. Meaning there has to be probable cause to believe that the person being charged committed a crime.
2. This case is so beyond needing Kara to testify against Ludwig, especially in exchange for immunity. Please. Ludwig has confessed to the crime, including to the fact that it was premeditated. Kara's sister was an eyewitness to the murder of her father and heard the shot that killed her mother. Police found the murder weapon under the front seat of his car. There is evidence that Ludwig had told people in the days before the crime that he "could kill someone and get away with it." Police say they have already found over 400 pieces of potentially material evidence on Ludwig's and Borden's computers.
In what Reality?
