If the major is not professional, it is difficult for the parties to judge, and the experts in the industry judge more accurately. But you said, I am a family member, where I have the ability to judge. From the appearance to provide you with a few reference standards. First, criminal lawyers pay more attention to criminal substantive law and criminal procedure law. For example, several judicial interpretations of drug crimes should be memorized. How many grams of methamphetamine is a pill, how to determine the number of drugs, and how many grams of methamphetamine can be sentenced to death locally. In addition, in order to understand a legal fact, how is the general evidence chain closed? In terms of procedure, confession and punishment, confession and non-punishment, how to choose, and what will be the consequences. Second, criminal lawyers handle more criminal cases than ordinary lawyers. In first-tier cities, there are even criminal defense lawyers for economic crimes, criminal defense lawyers for property infringement cases, and criminal defense lawyers in most areas have participated in various criminal cases. Of course, there are still relatively few lawyers who only do criminal defense and do not do other cases. How to judge that more criminal cases have been handled? I think you can get a general idea by searching online refereeing documents. You can see the lawyer's defense. If most of the opinions are "first offenders and accomplices", then there are not many special opinions about the defendant who is defending, and he is not a very professional criminal defense lawyer.
On the other hand, there are several misunderstandings. First, those who often say that most of the crimes are innocent or light are bragging, because investigation organs, procuratorial organs and judicial organs do not often make mistakes, and criminal defense lawyers protect the rights of the parties. Of course, innocence and light crime are the best results, but it does not mean that guilt does not protect the rights of the defendant. Most of them make the sentence as short as possible through the efforts of lawyers and communication at the procuratorial stage. Second, I claim to be familiar with the public security law, and such lawyers have to be cautious. The third is to look at age. The older you get, the more experienced you become. This is a big misunderstanding. Now some young lawyers can handle three or four cases well a year as long as they are willing to study and study. On the contrary, some older lawyers neglect their studies and make some jokes.
