That sequence in Madonna's current tour which sees the singer attached to a crucifix style construction has, of course, caused controversy in a number of countries, but might lead to actual prosecution in Germany.
Prosecutors there have confirmed they will monitor Madonna's shows there this week to ascertain whether the mock crucifixion scene amounts to "insulting religious beliefs", which is a crime according to German law.
However, authorities do not seem to be taking the routine too seriously. They have said they plan to rely on media reports of the event rather than sending their own officials, and it is doubtful whether such reports would actually be sufficient to pursue legal proceedings.
As previously reported, the routine has already caused protest from a number of religious leaders, though Madonna continues to defend it. Her spokeswoman told reporters recently: "The context of Madonna's performance on the crucifix is not negative nor disrespectful toward the church".
