Who's Hallowed at Halloween?

Members of a church in Bloomington, Indiana, have been distributing fliers in their community warning people of the dark side of Halloween. One woman, whose yard is decorated with witches, skeletons, skulls and grave markers, took offense to the flier titled "In Praise of the Devil?" and . . . called the police: "I started reading it, and I was very, very upset by it. I found it very accusatory and very threatening." The church's pastor said that they didn't mean to upset anyone and only wanted to tell people that this holiday isn't all innocent fun. So how should Christians respond to their neighbors' fascination with Halloween?
