body: Is it likely that a person could be arrested for verbally stating that they wish they could be sharp enough to commit a huge crime, in front of a policeman?
  
  
  For example (and of course it depends on the jurisdiction), would I be arrested if I say a thing like "I wish I was able enough to steal billions from the bank"? 
  
  
  Jurisidiction: UK, US, Italy.
