Hold on there. Facebook is anonymous? I haven't seen the kids page, but who is to say he didn't have his name and city, maybe an e-mail address or two on there.

Go this group page I want to kill my teacher! and click on almost any members page where you can typically find their first and last name as well as their hometown. Why would it not be legitimate for law enforcement to scan all members pages for more specific threat language and investigate?

A first and last name, typically a photo and a hometown is likely more than enough to identify a subject -- throw face recognition and a database of school id photos and you are good to go. I don't see anything wrong with that.

Does someone out there thinks there is an expectation of privacy for data they post on the internet?

I thought that was exactly what you should NOT expect.

...and I've seen numbers as high as 20% is some countries and even counties in the US.

Try to find a comparable, available position in your city. I'm not as in touch with how IT position availability is, but the scene is not very pretty out there in general.

Keep working while you look for a better situation and improve your resume in your current position.

There was a Seinfeld episode where Kramer went into the post office to stop sending him mail - got me thinking. Why do we have to receive all this crap in a box in our front yard? I pay my bills online or schedule checks from my bank each month. There are few items that I actually open up every month, most go straight into the trash. The items I do open I end up scanning into PDF anyway as invoices or paystubs.

I actually pay for a service like this: Earth Class Mail, there are few others like this too. They receive your mail and scan the envelope which you access online just like your e-mail, then you can pick it up (inconvenient) or scanned, forwarded or shredded/recycled. It's a bit expensive and I've only been doing it for a couple months but so far so good.

I have a real street address (no PO Box) which so far no one has balked at: the DMV, my insurance company, voter registration.

Of course, the reason I am doing this is so that I can live anywhere I want without having to change my address every time I move -- except for magazine subscription (which with the new iPad/eReader devices will hopefully not be needed anymore). I work remote and can take my phone number anywhere I go (skype, vonage, etc) and make or receive calls from my laptop.

We all got that CD. The rest of us just had the good sense not to post it to /.
