body: On a recent foreign prank show the following scenario took place.
  
  
  A group are dressed in realistic [Hazmat suits](https://en.wikipedia.org/wiki/Hazmat_suit).
  The group are scanning an area with fake [radiation detectors](https://en.wikipedia.org/wiki/Particle_detector). 
  
  
  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?
