Someone at another forum I visit pointed this out:
Binghamton, NY shooting. Shooter: Vietnam
Virginia Tech. Shooter: South Korea
Case Western Reserve University. Shooter: India
Wisconsin Hunter Massacre: Shooter: Laos
Trolley Square Mall Massacre: Shooter: Bosnia
Appalachian School of Law spree: Shooter: Nigeria
So...going with the same logic of "ban guns!" we must act swiftly to ban all immigrants.
