The Supreme Court ruled unanimously Monday in favor of the Secret Service over its 2006 arrest of a man who heckled and allegedly shoved then-Vice President Dick Cheney.

Steven Howards had heckled and touched — some witnesses said pushed — Cheney while he visited a Colorado shopping mall, and he was arrested for harassment. Although the charges were later dropped, Howards sued the agents who arrested him, claiming they had done so in retaliation for exercising his First Amendment rights.

The high court found that the agents had legal immunity and also that it had never recognized a First Amendment right not to be free from a retaliatory arrest backed by probable cause.
