Dublin (CNN)Emily Faulkner is in central Dublin, handing out leaflets featuring fetuses in various stages of development, when she's pelted by an egg.

Covered in yolk, she turns to her fiancé, Nathan Berning, who has a GoPro video camera mounted on his chest.
"Did you get that on tape? Is it on, babe? Turn it on," she says.
As Faulkner wipes the mess from her face, a fellow anti-abortion campaigner approaches her, saying she'll be calling the police to have a look.
"Ok," Faulkner says with a smile. "I'm excited."
With just days until Ireland votes in a referendum on whether to repeal the Eighth Amendment to the constitution -- which places the right to life of an unborn child on equal footing with that of the mother -- campaigners have become increasingly confrontational in their tactics.
    If a majority vote Yes on Friday, Ireland is expected to enact legislation that will allow for terminations up to 12 weeks into a pregnancy. A No vote would keep the country's abortion laws -- some of the most restrictive in the developed world -- in place.
    But not all of those targeting voters with leaflets, placards and social media posts are Irish.
