How do criminal lawyers write letters?

When writing a letter to a law firm, honorifics are not very important. If you want to add them, you should decide according to the contents of the letter. If you write a legal opinion, I think at the end, "Is the above opinion inappropriate? Please reply. " Or write "I hope to give legal advice on the above facts, thank you!" In other words, if the letter to the law firm is to solve the problem, just ask it directly, without being too polite!
