(I posted this on a couple of other threads, also.)
Here is a screen cap from the video at MyFoxTampaBay. This guy was right up front and his tee-shirt caught my eye. "Union Tough", it reads.
Now, I know it is just an old union slogan, but this guy chose to wear this particular shirt, on this particular night, for a particular reason.
He wanted (or maybe his Union boss wanted) to intimidate people into sitting down and shutting up. Unless, of course, they agreed with the party /union line.
From here it looks like “UNION THUG”.
