I'm in Georgia. What is freaking us out is that it was reported in the local rag that captured terrorists had pictures of some of our schools.
I remember that story because one of the schools was the county next to ours. It turns out those guys in Iraq had plans to schools because they were building schools in Iraq, not because they were planning terrorist attacks in Georgia.
When I was selling for Grollier in the mid 70s, it was common practice to get leads and info like that from the schools in exchange for free Grollier products.
What does disturb me is the sheriff's response of being so quick to dismiss the matter.
I would call the sheriff's dept. and find out if the deputies who investigated the matter asked the man who his employing company was, etc, and follow up on this yourself.
