Thanks for requesting and post that information Nova Land. I think we can clearly conclude that Misty Newburry was not arrested for praying.
The irony of it is that even if DOC had (for once) gotten his facts right, it wouldn't have mattered. Police make mistakes -- that's why "false arrest" is on the law books. School administrators make mistakes, too. The ACLU has a long history of suing govermental entities that wrongfully deny people and groups their "free exercise of religion" rights, and DOC could, if he wanted, pull something like fifty cases off the ACLU website where some idiot administrator made the wrong decision and got slapped down.
And it still wouldn't mean anything about whether or not the United States was a "Christian Nation" (it isn't), or whether or not the "Separation of Church and State" is a Constitutional mandate (it is), or whether or not the Founding Fathers would have supported, or even permitted, state sponsorshpi of religion (they wouldn't have). Because isolated incidents are, well, isolated incidents, and the Founding Fathers even expected such isolated incidents to occur. Gee, I guess they weren't being stupid putting the right to "petition the government for redress of grievances" in that document, too. They expected that someone, somwhere, would screw up and step over the line.
The difference, of course, is that DOC isn't screwing up and stepping over the line. He's deliberately crossing it and then telling lies about the line not being there in the first place.
