Notice that headline makes no sense. That's because we are making a headline out of double-talk, also known as lying.
Protesters demonstrating against the "Security and Prosperity Partnership" were provoked by disguised police officers, at an attempt to incite a riot.
The "undercover police" were dressed as masked-men attempting to cross the line that the protesters were entitled to. One "undercover cop" was holding a rock as a weapon, which should have caused the riot police to act immediately, but they just stood by.
The union leader quickly noticed that they were being set-up and called them out by saying, "These three guys are cops, everybody!"
He was right.
So is this how police should be used? Are they in the kind of field where you want to drum up business? That's what they were doing.
The corruption is displaying itself for all to see.
