Black Flag

There seems to be several flavors of black flags flying above the world's terrorists. Here's two.

ISIS?

Jihadists?

Reading about a hostage situation is Sydney (warning: it will eat your computer), I noticed this post script:

In August 2014, British Prime Minister David Cameron declared anyone carrying The Black Standard could be arrested.
It is also banned from public demonstration in the Netherlands
The use of the image the flag for non-educational purposes is forbidden in Germany.

I wonder how that might play in the USA. This might not be the time to quote H. L. Mencken.
