Is doing an action like chalking or flyposting going to get me arrested?
You are highly unlikely to be stopped whilst doing this type of work in th UK.
If you are, it’s more likely to be by people who work in the industry rather than the police. Avoid giving your name or details to any industry worker. You’re only obliged to give your details to the police, and even then, only in certain circumstances.
The situation varies depending on external factors and location, particularly in countries with different laws. Spray-chalking usually provokes the police if they see you do it. There have been incidents of rebels receiving a fixed penalty fine of £90 for chalking outside a company HQ.
In the worst case scenario, a charge is likely to be that ‘criminal damage’, which holds minor penalties.
