Slow down Scot, you don't need to respond to every jab at the British empire.
I am sorry, but to try and suggest what you did was just silly. The screaming (mostly female voices by the sound of it) was from people scared by a sudden volley of gunshots. Most people scream in such circumstances, its human nature.
Guns started firing and most people there became terrified, and terrified people panic and scream.
To try and suggest they screamed out of some Islamic ‘sympathy’ is probably the most nonsense thing I have read on FR in the last 48 hrs since the murder/shooting. And thats saying omething.
