Amos's first response "Wowser, SH -- you've had a day." surprised me. I read the whole thing as a copy 'n' paste. Unless I misread it, none of the above happened to Springhopper. His post starts:
"This was from the Friends of Florida Folk list today:
I have no idea what is being reported on the news around the world
about what went down in San Francisco today but here is my eyewitness
report."
Springhopper does not appear to be claiming it as his eyewitness account, and has not re-posted to confirm or correct any opinions.
These happenings in San Francisco were noted on a site for 'Friends of Florida'.

Am I alone in feeling that this is much like the start of an 'Urban Myth' / "This didn't happen to me, but I got the account from someone known to a friend."
Even the author of the piece doesn't claim to have witnessed the baby taking, it is at yet a further remove. I.e. it was heresay/Urban legend even before the author got to it, yet alone this re-post.

Or am I just overly cynical?
