Bah!
Yes, the danger of pranks like this backfiring due to over-credulous loons is always present.
I remember once when as a university student I helped start a rumour that there was a surplus of fresh baked bread in Czechoslovakia. The Russian newspapers got hold of the story, things got out of hand in an eyeblink and it ended up in the invasion of Prague by Soviet armoured units.
I certainly learned my lesson, I can tell you.
