On a recent foreign prank show the following scenario took place.
A group are dressed in realistic Hazmat suits. The group are scanning an area with fake radiation detectors.
The detectors are set to emit a sound that indicates danger, more specifically high levels of radiation.
When the detectors emit the sound, the group run away making a scene to ensure the surrounding public take notice and react.
All of this being a façade to purposely incite fear in to the public.
I am sure that this wouldn't be tolerated in most countries, and would be breaking the law.
Which laws would cover this behaviour?
