Perhaps I'm misreading his reference, but I don't think it was about Foley.

Rather in the last week or two, there have been 3 seperate gunman attacks on schools through out the US, and security has been stepped up in a number districts to be watchful of strange people hanging around schools.

Bingo!
I heard about the Amish attack.    The more paranoid people claim that attecks happen all the time, and are just never reported.

At one time I saw a bloody body in a fed building, men in body armor and guns standing all about, film crews for the local TV channels were there, yet not a peep from the media.   So I'm a little more willing to believe the position of attackes not reported, based on my own lying eyes.

Pheeeer of the Eeeeevil gunman and me being a threat implys the use of obeservation of the outside of the school AND people who cared enough to to be doing a job to call in my walking about on land my tax dollars pay for.    Rather over the top if one feels one has to call in someone walking around the back of a school or driving about a school.

I just would have wipped out the incident report number, explained why I was there, then bitched aobut the lack of bicycle racks.
