Identify and connect the pictures.
The connect is Ku Klux Klan.
The first pic is of Nathan Bedford Forrest, who was a member [and allegedly the Grand Wizard] of the KKK.
The Adventure of the Five Orange Pips is centred around the KKK.
Forrest Gump reveals in the opening scenes, that he has been named after Nathan Forrest.
Kudos to Shridhar, who got the 3rd connection.
Credit to Nidheeshwar and Rahul for getting the connect right.
