That behaviour is already against the law. This is exactly the idea of this ghastly 'consultation', to use the guise of 'stopping the travellers' to criminalise what we've all been doing for decades. It's the thin end of the wedge, leveraging bigotry towards travellers.
Yeah but not everyone follows the law.
It's not pragmatically effective to enforce, for example, littering a field, as you need to prove who did it and even if you can do that the sentence might only be a fine which wouldn't get paid.
The difference between the proposed law and the existing law, is the proposed new law allows for prevention rather than cure.
(bikepacker's post sums up my feelings (and the truth of the situation) exactly, probably better expressed than I would)
Never in the 20 years I have lived here have I found any objection to a passing cyclist or walker wild camping within this area.
So what reason is there to criminalise them?
The point is to give the law sufficient teeth to make it effective.
In order to do that you may sometimes need to give it
more teeth than it needs for all situations.
You appear to want the law to be hamstrung for fear it will be used incorrectly, and if anyone has their land ruined because of it, well tough - they probably deserve it for being "rich" enough to own the land in the first place.
This is a radical change in the law which affects all of us. I don't want anyone walking up on me with a gun that is clearly being borne in order to cause fear and to intimidate, let alone pointed at me.
I think put simply you don't really have to worry about that if you aren't intending to be antagonistic or confrontational towards anyone or damage their property. If you're very worried about that you may have to ask whether that is your intention.
