Advocacy

The police aren't very experienced and don't know the law very well, but they can also challenge the case, etc. Sometimes the attorney's recommendation is rejected, in which case I can file a lawsuit (complaint) against them. It's easier to defend your client in a pretrial detention center, but not 100%.

In court, it's much more difficult—the questions, the process, and the analysis are all more complex. Not everyone agrees with the lawyer, and you have to prove your point.
The judge must also be smart and most often a former lawyer.
