Sorry guys, but I just saw a photo where you CAN see the blood on the road aswell, making my main point invalid, so until I know better I will trash the Woolwich false flag post. This is all very confusing, and rather than say something wrong I chose not to say anything.
As you can see the blood stain is also visible from ground level photos from when the two Negroes were still there (you can also see that the “white t-shirt” is not a t-shirt at all, but the victim’s white skin);
