Because jumping to an immediate conclusion that a crime has religious/race/minority grounds perpetuates prejudice.
It allows a moral panic to flourish and long after the truth comes out the germ of the idea that some woman was beheaded by a terrorist grows into an urban myth that sticks around for ever.
you one of those.
I would wonder, how many people like myself, saw that headline and in split seconds between running after small children and all the other things I have had to do today, thought, Oh God, Terrorist.
Then, a few moments later when I checked the actual story, thought, No, Not Terrorist, random attack, poor soul.
Its certainly clear now what happened, and I am sure 99.9% of others are also clear that it was not terrorism, this time.
Mrs devere, if your so worried about this sort of headline, and people jumping to conclusions about terrorism; Don't Moan to us, that it isn't fair.
Complain to ISIS. It is ISIS who are creating the current climate of fear and its ISIS who are beheading people and slaughtering them and inciting British Muslims to do the same from their own homes. Also complain to Lee Rigby's killers who killed him, in a run down boring part of London, in broad day light. Complain to ISIS that because of their actions, when someone is Be headed here and the headlines are as above, the public will in milliseconds jump to the wrong conclusion.
And that upsets people. ( not the actual act of violence, just the associations it may provoke for all of two seconds)
