The American Center for Law & Justice is hardly an unbiased source, I don't believe much of it, BUT, say there is a longstanding prohibition by the Capitol police against public demonstrations within the Capitol building, and they interpret that to mean no praying,

SO WHAT?,

as related, they were not prohibited from praying, just from making a public display that might be offensive to some and disruptive of government business. I don't necessarily agree with the policy, but how much work do you think would get done in Congress if every group that wanted to demonstrate were allowed to do so in the Capitol? Anti-abortionist praying, anti-Gay & Lesbian praying, even as noted anti-Masonic praying! It would never end. How has this minister been harmed except in not being allowed to fulfill his desire to make a spectacle of his faith?

If, in fact, this other Misty girl was indeed maced, handcuffed, etc., then justice prevailed by her being exonerated and compensated. I'd say the school administration erred in that instance, given these facts, but what was the context? was this right after Columbine shootings? or some other 'high alert' period? Was there some other history between this girl and her school? if not, the grandmother just happened to videotape the proceedings? or did she know that this was provocative and bound to cause a ruckus? again, anecdotes are anecdotes, & often colored a particular way, not always reliable. I don't believe everything printed in the Congressional Record, either, from a government that says it lies to its citizens, or maybe they were lying when they said that!
