Declaring war when enemy spy is killed. Which is the warmonger penalty?

Question

In Civilization V, whenever you catch a spy trying to steal a technology and identify who his master is, you are presented with three options.

1. To forgive them for spying on you

Which gives a diplomatic boost with that civilization.

2. To ask them to stop spying on you

Which results in a diplomatic penalty with that civilization.

3. To declare war

Warring is often difficult due to the warmonger penalties. I know that whenever one declares war on a civ teaming with another through 'Should we declare war on...?', the warmonger penalty is halved.

Know that the Warmonger Penalty is cut in half any time you have agreed to go to War against a Civ at another's request, or asked them to do this through the Diplomacy interface (Shall we declare war upon...).

Question:

Is the warmonger penalty for declaring war upon discovering a spy, reduced by the fact that you just caught them spying?

Answer 1

Put simply: no.

Every time you declare war on a Civ you gain 250 flat warmongering "points". This is just a raw value that represents your warmongering level which is then adjusted for individual Civs based off of their leader's warmongering-hate level.

Sort of interested in your source for the team war declaration causing halved warmongering - it's my understanding that you simply get a flat warmongering score from declaring war, however the city capturing points can get halved based off of war statuses between civs.
