Yes, I think it's a generally rare occurrence to be confronted this way about one's belief in God in the US, having lived here most of my life. Perhaps the circumstances warrant it, but I think the statement that the nurse had "never seen a Canadian there before" and that her plight elicited that statement from the nurse is farfetched, seeing as the nurse would have seen much much worse from other detainees.
The story is pretty incredible on its face, so I don't see why some skepticism on the way it's being reported isn't justified, especially in the face of reflexive hysteria over a descent into fascism we're supposedly facing.
Again, if true, it is disgusting, and I'm negatively disposed towards ICE and the CPB in general. But I'd like to know whether this is a case of a really odd situation paired with bad judgement and/or bad advice, or something much worse.
