Essentially... if you are ashamed of your own speech to the point of hiding it behind locked doors and the first amendment then it deserves to be exposed. This Officer is in the business of protecting the public, he was merely carrying out his duty. If the Officer crosses the line and arrests this teacher, then I will come to the teachers defense to keep him out of jail.
I think that we read WAY too much into the 1st Amendment. There are no guarantees that your speech wont cost you your job, it's just a guarantee that the government wont put you in the slammer for opening your trap.
Why don't we start asking the teacher some questions and worry about the cop, later? After all, which of these two issues is more important to America?
Anyone who thinks "trespassing" is more haneous than "Communist Propaganda", really needs to re-evaluate what America and Freedom is all about.
Uh, this isn't a first amendment issue - this is about a on-duty cop going outside his juridiction and entering a building where he had no business going. As in the 4th Amendment. And the 4th was passed EXACTLY because folks like you are willing to overlook official misconduct to further your own political agenda - the first step out on a very nasty slippery slope.
