Snopes is probably not infallible but they sure do a good job. I have never seen them be outright wrong, although they don't have time to add all the twists and turns of all the stories or to cover everything. People should check all the sites when in doubt and even their own sources.
Wikipedia, excellent as a broad ranging source, is riddled with urban legends and other mistakes so you have to take everything on it with a grain of salt.
Snopes is so highly used because of it's extensive history and significant and extensive archive. Snopes was started in 1995, and it's founder had an online history that went back even further, having been active on USENET newsgroup alt.folklore. Urban The site is even thought highly of by well known academic folklorist, Jan Harold Brunvand.About.Com was started in 1996 but only changed it's name and to and registered about.
Com in 1999 was usually never seen as highly comprehensive, as each topic usually only has one expert or guide covering it.Truthorfiction. Com was registered towards the end of 1999. Urbanlegendsonline.
Com was registered at the very end of 2003. While wikipedia is an excellent, very comprehensive site -- it cannot be trusted to disprove urban legends or other folkloric legends as the very nature of such legends and memes would make it so that they would occasionally be interjected into such user edited pages.As far as the story you found and are mentioning that you got confirmation of from the police and the FBI, can you please list it here? I suspect that the reasoning it's appearing on snopes is based on the way it's being replicated folklorically.
Also, personally I do _not_ trust 'official' sources such as the police, etc.Or expect them to be infallible when it comes to urban legends. I've seen faxes and other publications from such 'official' sources such as various police departments announcing things which are clearly urban legends to be true. Anybody can fall for an urban legend, and it doesn't help when authority figures are passing them off as true because they fell for it too.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
