The Meaning of Knife

You set off for Rome on your quest to find the ChristKnife. The man you seek is in St. Peter's Cathedral. You get near the church and find that, in order to get in, you'll have to get past metal-detecting screening devices. S---! You have a bomb strapped to your chest (in case any men get to close to you!) Do you try to pass through security or go around the fence near the shops and simply walk in?
