1. The word you're looking for is repeal and we can't do it because HRA is there because of the European Convention on Human Rights (ECHR) so don't bother with that idea.
2. Why don't you change the record about local councils abusing the system. They're not - Councils can't intercept comms because they don't have the powers. They do have the powers though in terms of preventing fraud, flytipping, abuse of systems and other areas. It's all very well politicos saying that more care is taken but they don't have to justify the actions against the public purse.
3. How do you define petty issues. What if a family was pretending to live in one area to get a school place only to "move" the day after their child gets the place? Should a less well off family suffer because of that? If fishermen were destroying fragile shellfish beds because of their greed, why shouldn't the Council act? You're not going to get people to fess up, so other methods need to be used to obtain the evidence.
4. I'd bet if someone dumped the contents of a house in your garden or land, you'd want them stopped or arrested. You'd still have to get rid of the stuff yourself though. The local authority will probably move it at a cost if you ask nicely.
AC for good reason but, yes, I do work in the public sector.
