First Amendment is memorialized? It seems to me that people who devote their lives to the service of the country have at least as much right as the rest of us to speak their minds.

It is beyond ill-advised to use any cell phone - govt issued or otherwise - to send written statements that might come back to bite you one day. I wonder if people will ever figure that out. That holds true whether you are texting your drug dealer or your boyfriend. But a federal employee is forbidden - I assume you mean by law - from speaking their minds? Can you support that? I doubt it would stand up to Constitutional review.

Only people who are desperately seeking to discredit an investigation assert law enforcement people must not have opinions. Of course they have opinions. They need the professionalism to keep them out of their work. Which was the conclusion here.
