@gollum,
Certainly, I'm no lawyer..and you seem to be getting at something...re your own legal background. What does that link have to do with getting a list of names of people on the Social Security disability program?
I have had a brief career working for a company, div of Motorola, who provided access to internet and databases for police and gov't agencies with interface to license, criminal records, fingerprint, etc., and public safety info. I was only aware of access being granted to FBI, public safety and police forces. to my knowledge, it is not just paying for access..there has to be a need to know.
I have strong doubt that an employer or someone with money can just be granted such info. Are you aware of something I'm not?
