According to Amazon.com, “Incidents of Travel in Central America, Chiapas, and Yucatan” was first published in 1841. The Book of Mormon was first published in 1830. Are you suggesting that in writing the Book of Mormon, Joseph Smith plagarized a book that wouldn’t be published for another 11 years?
Read the article please, it explains your misconception. That given, it would not be out of character for smith to try to use such material to support 'later revelations'.
