Mods: This may end up in IMHO territory, but there may be a factual answer, and I am not asking for legal advice.
Why is hearsay testimony always inadmissible in court? At least on TV that seems to be the case. I understand that it’s not the same as the defendant testifying that they said something, but why can’t it be admitted for what is is?
Hypothetically, if a friend walks up to me and says “I’m going to kill my parents”, and his parents later end up murdered, the fact that he told me that he was going to kill them should count for something. It doesn’t prove that he did it, but it certainly shows intent. Yet I’m pretty sure I couldn’t get on the stand and say what my friend said to me since that would be considered hearsay I assume.
Secondary question: If I had secretly recorded the conversation mentioned above would that recording be admissible in court?
