William Charlton could be considered a genius in the criminal world, not only directly challenging the British Government, but also successfully evading punishment after being caught red-handed and imprisoned for the first time.
An important reason he was able to do so was because of the ancient and troublesome issues preserved in British law, which made it necessary to overcome numerous obstacles in order to prosecute criminals.
Of course, William Charlton himself was cunning enough in this regard, accusing the Mint factory of making personal grudges on one hand and saying that he was arrested because he had offended the factory.
On the other hand, he bribed several witnesses and used the money made by producing counterfeit money to find people of sufficient status to testify that he was in Scotland at the time of the crime.
