Oklahoma Gov. Brad Henry has signed a Senate bill into law that targets "eco-terrorists."

The law makes trespassing onto a site where animals are kept and "disrupting" operations a felony. Punishment includes jail time and up to a $10,000 fine.

The bill passed both Oklahoma House and Senate bodies overwhelmingly.

"The governor believes the legislation strikes a good balance between commerce and environmental issues," says Rep. James Covey, D-Custer City, House author. Covey said the bill is aimed at heading off actions by radical animal rights groups.
