Logic Does Not Apply

Friar Laurence and Juliet, somehow, both think they have a perfect solution to their problem. Instead of telling everyone the truth about Juliet's secret marriage to Romeo, they think it's a better idea to have her fake her own death, have Romie sneak back to Verona and break into the Capulet tomb with the Friar before running away with Juliet. In what messed up world does that plan make any sense?!?!?!?
