10. John Hinckley
If you are a fan of the actress Jodie Foster, you will know a bit about John Hinckley. John attempted to track Jodie Foster for years stirring up a lot of attention and then went on to try and murder President Ronald Regan.
He targeted Regan in order to impress Jodie Foster, and was taken into custody shortly after his attempted assassination. He was sent to a mental hospital and released in 2018. He now says he has changed and spends most of his time volunteering at a church.
