No.2. Am I required to notify police officer of this recording?
The admissibility of any evidence into any legal preceding is at the discretion of the judge. Generally speaking, video/audio recordings are admissible if they are deemed relevant.3. If there is not is this Recording admissible into court proceedings?
It's your call. I can see valid points for going either way.4. Is there a benefit of not notifying police officer I am recording conversation?
