http://www.upi.com/Odd_News/2009/10/21/Officer-claims-alien-encounter/UPI-79601256162328/ Now, I admit, I'm not an alien expert. But I think this cop has wrongly diagnosed this one. Those don't sound like aliens to me. Blonde hair? Very tall? England?
It's obviously the Sidhe.
I think what this man needs to do is hang an iron horseshoe, and maybe leave out some milk at night, and everything will be fine.
