"Now look, Judge. Trials are rarely about the truth. The D.A. distorts, the defense distorts. Why shouldn't the client be allowed to put in her version? After all, it is her life on the line." In order to get her innocent client off, Harry must put her on the stand to testify, but the client has said she plans to lie in order to protect the real culprit. If Harry lets her testify, she'll be suborning perjury, and if she doesn't, her client will surely be convicted, so she must do everything in her power to get her client to tell the truth.
