Don,
At any moment a terrorist atrocity could make you look like a misguided dupe, but it does not prevent you from expressing your opinion publicly here.

As for the judges, they are made unsackable to ensure their independence.

If the police can not supply evidence to continue detention, no one could blame them for ordering release.
If there was doubt, I would hope that they would err on the side of caution and safety.

A similar situation happens now, as judjes frequently over rule police opposition to bail, and there have been plenty of cases of bailed criminals committing serious crimes including murder.
