For the non-attorneys here, we have Miranda warnings. Anyone that watches the show Cops knows them. "Anything you say can and will be used against you in a court of law." Not "for you." "Against you."
Reporters, like Police are expert interviewers. You're not going to successfully BS them 99% of the time. You will likely say something dumb. Sandusky is a public speaker. He knows press conferences. He's good, but this isn't a coaching field. This is criminal law and procedure mixed with evidence, and he's out of his league.
Ever notice most attorneys accused of criminal activities keep their mouth shut. Even we don't win battles in interview rooms. Most of us are smart enough to know it.
I tell clients don't talk to LE without a lawyer present. And, if you are called to a Grand Jury, make darn sure you know every statement is accurate and if you can't do that take the Fifth.
But holding a press interview while charges are pending is just insane.
