Criminal defense is a highly professional job, which requires lawyers not only to have a solid theoretical foundation of criminal law, but also to have meticulous logical thinking, keen insight, rich social experience, inferential understanding ability, and increasingly accumulated practical skills. Otherwise, it is impossible to have a high degree of professional sensitivity, find the breakthrough point of case defense, accurately convey the lawyer's defense thoughts to the defendant, and skillfully respond to the questions of the prosecutor and the judge through the lawyer's defense work, so as to correctly handle the relationship between confession and defense. It can be said that lawyers' interest and investment in the field of criminal defense will greatly enhance the breadth and depth of their thinking, enrich their thinking perspective of defense, and greatly stimulate their potential to learn and sum up experience, which is directly related to the success or failure of lawyers' defense. Therefore, lawyers who take criminal defense as their development direction have much stronger theoretical and practical operation ability than ordinary lawyers. I believe that in a word, there is specialization in the industry, and only professionalism can be trusted. The lawyer published professional articles in legal journals or newspapers, or published monographs to explain his in-depth exploration and research in this field, which reflected his accumulation and precipitation of knowledge in this field to some extent.
Excellent criminal defense lawyers can make full use of their flexible grasp of criminal law theory and rules. On the one hand, they disintegrate the evidence system of the public prosecution, blur the facts of the crime and weaken the accusation of the public prosecution against the defendant. On the other hand, through the loopholes in the existing evidence and the evidence collected by ourselves, the circumstances of the defendant being given a lighter punishment are strengthened, so as to persuade the judge to adopt his defense viewpoint. Legal basis: Article 38 of the Code for Lawyers Handling Criminal Cases, with the consent of witnesses or other relevant units and individuals, defense lawyers can collect evidence related to the case from them; If the respondent disagrees, it may apply to the people's procuratorate or the people's court to collect and obtain relevant evidence, or it may apply to the people's court to notify witnesses to testify in court.
