Felony Murder Puns

A few years ago, there was a series of murders that seemed completely independent from one another, aside from two similarities. Each of the victims had received an e-mail the day prior that was typed in all caps, and contained a joke, with the punchline being a play on words. The victims also all had felony convictions. In light of the second fact, many people felt that the murderers were doing a service to the public. Many others disagreed, however, and those against the murders all rallied under the same slogan: End Capital Punishment.
