How does telling a person their Miranda rights excuse the cop from recording everyone else while making it illegal to film the cop. Rights don't switch off and on like a toggle.
The Miranda rights are logically STILL applying to the cop at all times and as such anything they say and do can be held against THEM in the court of law such as recordings.
How does this make a cop immune to being recorded? Why aren't security cameras illegal? If it's because of a sign saying they're recording you then why cant a citizen have the same?
