I would wait until the prosecutor filed charges before hiring an attorney, especially since the DNA tests came back negative.
These parents are wasting their time and money at this point. The prosecutor isn't going to get an indictment on the evidence he currntly has. Bennett is cetainly not motivated to resolve this case quickly.
Just tell the cops to leave you alone unless they have an arrest warrant or search warrant.
This is the exact reason you do not talk to the cops or volunteer any information. If you didn't do anything wrong or didn't see a crime committed, there is no reason for them to question you.
You talk to them and the next thing that might happen is you get put into the same position as Scooter Libby. They'll try to hang some sort of 'false statement' charge on you; then your troubles will be just be beginning when you did nothing wrong.
If I was one of those players, I would have simply told the cops, "I don't have any helpful informatin because I didn't see anything going on related to the allegations. That being the case, this conversation is over. Goodbye."
Cops will lie to you about what others might have said in order to get you to keep talking. When they do that, just tell them you don't know anything about what others may or may not have said.
Some people will say that this approach to dealing with the cops may make you look guilty. No it won't. It will just save you a lot of problems and a ton of money in legal bills.
