Honestly, feels like the company is within their right to press charges here? Dude is disabling the equipment that they use to turn revenue, no?
Don't agree with the company, but I don't find a suit here ridiculous. If my job put up cameras, and my form of protest was to deface and disable them, I'd get fired. This isn't a job, it's government, but it's similar in my head. The people with the authority to do something did it.
I don't think this counts as property damage or vandalism because nothing is damaged or vandalized.
Part of putting shit in public is that it now has to interact with the public. If you want your stuff pristine, I would think you should not put it in public.
Maybe the law disagrees with me here, and it probably does because this country bends over backwards for companies, but that's how I see it.
