Behind the scenes
The Professional is a reference to the French movie Léon, also known as The Professional and Léon: The Professional. In the movie, Léon remarks that "rifles are for beginners" as they let you keep a distance from your target; a true professional gets up close. The plant next to the Vault Boy is also a reference to the movie. Also, the clothes, hat, glasses, and face stubble portrayed by Vault Boy are identical to the character played by Jean Reno in the movie.

Bugs

 * The portion of this perk meant to confine the bonus to apply only to sneak attack criticals is set up incorrectly: rather than checking if the target has detected the player, the perk mistakenly checks if the player has detected the player. Additionally, there is no check in place to ensure that the target has not been alerted without overt detection of the player, nor is there any check to ensure that the player is currently sneaking. Due to these issues, the perk applies to all critical hits the player inflicts.
 * Despite being one-handed revolvers, That Gun and Police pistol are not affected by this perk.
