You may at that. Personally I believe that in politics perception is often reality. If those who wish to misconstrue your testimony are successful you can easily wind up the goat. Would you, working for somebody such as President Bush, want to be the goat for their decisions?Well, being "miscontrued" by politicos, and being charged and convicted of perjury by a jury, are two very different things.
I don't believe there is any danger, and for me, being accused of something I did not do, would be my paramount concern. If I were telling the truth, I would feel well-armed to do battle with anyone whom might want to "misconstrue" me.
There are times when discretion is the greater part of valor.
