Cosmos Liturgy Sex has a post about a some people who damaged a marble altar a the Annunciation Catholic Church in Morgan County, Alabama. They claimed biblical authority for doing so and consider Pope Benedict to be the antichrist.
Various penalties were imposed by the circuit judge, Sherrie Paler, including a 2 year suspended prison sentence and payment of restitution. They pleaded guilty to "criminal mischief".
I could think of one or two other Churches where criminal mischief has been wreaked but the perpetrators have never been prosecuted.
