I don't think anyone was arrested - I can't swear to that, but the case has been generally handled as a civil case rather than a criminal one (even though criminal penalties can be imposed under these laws - the Judge has pretty much ruled them out in this case).
Police are not looking for people breaking these laws. Rather what has happened is that an Islamic group has chosen to bring a case under them.
I'm sure somebody could make a case against certain Moslems under this law, but so far nobody seems to have chosen to do so.
But there's nothing 'funny' going on. It's simply a matter that somebody really has to make a complaint for this law to apply.
f**king terrorists
