The savages in question were (as you can see from the video [1] here) well-dressed, happy about their work, and completely untroubled by the prospect of law enforcement resistance. Here is an update on [2] this story: the Iraqi reader who sent me the video writes this today about the photos above:

This was a small social club for us Christians that we spend our nights. As you see, we live very poorly and humbly. They had no reason to attack us. All we want is to enjoy a beer after a hard day of work. Is that too much to ask? Are Muslim minority in the West treated like this?

The photos above are from [3] IshtarTV.com, and there are many more photos there.
