I think it's 3ZA(1)(c) that's changed - by the Serious Crimes Act 2015 - in that this allows that an action can simply "create a serious risk of, damage of a material kind".

AFAIR that's different to how the act was prior to SCA2015. Indeed this section including "material kind" strongly suggests that the original intent was that the Act would punish material damage, rather than a trumped up suggestion by the CPS (on whomevers behalf) that an act might be reckless as to whether it creates an increased risk of serious damage.

This legislation seems to work like "well you went on a road near some property, which is exactly what a criminal who was going to destroy that property would do, so you're clearly guilty". It seems somewhat over-reaching to me.
