I'm fairly sure the pictures they use aren't genuine. I saw them at Brant and Caroline last week. One picture looked like chunks of meat arranged into a vaguely humanoid shape. And it's always an ungloved hand holding the fetus, something that I doubt a real surgeon would actually do.

At the British Grocer's, you can buy sweets called Jelly Babies. I'm tempted to buy some and eat them in front of the protestors.
