The first article does not say that councils own cameras nor that cameras are used for catching minor crimes. It does state that powers intended for serious crimes were, incorrectly, being used for prosecuting minor crimes and that it's possible that CCTV cameras were involved (though could have been park wardens). The third article says pretty much the opposite of what you state: there is absolutely a right to decline a law enforcement request (under GDPR) and that there is a warrant process ie a court can oblige you to. I can't access the second article but I don't live in Wales so they aren't my local force.
