Well we DO need appropriate and agreed-upon language

[FiveGoodMen]

to describe the level of treachery, betrayal and criminality that we're discussing.

Reminding each other what words are not technically correct doesn't solve that.

I should also point out:

trea-son
noun

1. the offense of acting to overthrow one's government or to harm or kill its sovereign.

2. a violation of allegiance to one's sovereign or to one's state.

3. the betrayal of a trust or confidence; breach of faith; treachery.

So, perhaps the legal definition is not the only appropriate use of the word.
