Legal question

Why did the police continue to question Jaime after he had been appointed a lawyer? Or, more specifically, why did the attorney allow his client to be interviewed by the police at all? Especially considering Jaime’s age.

The attorney seemed to have very little information about the crime or circumstances at that time. I know he told Jaime he could say “no comment” when he felt he should, and that he would be next to him to guide him, but that still seems like you are letting your client participate in a situation that could easily lead to incriminating statements. Why not just say, “I’m the defendant’s legal counsel and my client will no longer be speaking.”
