Isn't it the same as not asking for a lawyer after the crime of affray is released on bail pending trial

It's different. If you don't hire a lawyer, you may get an unfair criminal sentence. A criminal lawyer refers to a lawyer whose main business is to provide legal services for criminal cases. In criminal cases, criminal lawyers can defend their agents professionally according to the relevant cases and other relevant evidence materials learned from criminal suspects, which can effectively safeguard the vital interests of the parties.
