Lawyer's defense in criminal cases

Both will do. The defense can be written by yourself or by a lawyer. If you choose to write your own defense, you need to know the format and main points of the defense, and be able to clearly express your views and refute the other party's claims. Choosing a lawyer to write a defense requires full communication and exchange with lawyers, so that lawyers can understand their own situation and case background, so that lawyers can better help them write their defense.
