Excuse me, I want to find a lawyer in a criminal case. I can't guarantee what I can do before I pay the lawyer's fee. Is this a guarantee for me?

Paying a lawyer's fee is the cost of work. I certainly can't give you any protection. Because lawyers' work in criminal cases includes meeting, providing legal help, putting forward opinions on innocence and innocence. To make an inappropriate analogy, doctors charge first to save lives, but whether they can be cured depends on what disease they are suffering from. If it is cancer, it is at most remission, and the chance of recovery is very small, even if the effect is maintained to a certain extent.
