On today's Your Call, we’ll speak with David Kirby about his new book, Death at SeaWorld: Shamu and the Dark Side of Killer Whales in Captivity.

It also sparked a heated debate about whether the world’s top predator should be held captive. Join us at 10 or email firstname.lastname@example.org. Where do you stand on this issue?
