I like what CarltonBrowne the FO said; allow the SAFETY department to view these tapes. If there's a true safety issue, it can be dealt with. If someone says something that management wouldn't agree with, too bad for management. Just because you say something that goes against what one person says does not give that person the right to fire you. Now, if you're chatting about Porsche and Mercedes at 50' from landing, you're gonna have to explain yourself.
