I understood it was a hypothetical. My understanding was that if the same sermon was given in the UK it would lead to arrest. (and I was being somewhat tounge in cheek with the poster)
The Philly 5 were ultimately released. We have bad apples here in the US...the prosecutor that authorized those charges should be disbarred - you just don't arrest people under those circumstances.
While the UK is clearly not free...MHO is that the US is just a shade behind you.
G'day.
