Telling half the truth is often the biggest lie of all.
As a Criminal Police officer in the Major Case Division, the most formidable opponent I ever encountered embodied this saying perfectly.
She was a Prostitute.
After being apprehended, she confessed readily. Every word she spoke was true, yet she skillfully avoided all evidence that could convict her.
I joked that she was even more impressive than a Law Professor.
Later, I discovered that she really was a Law Professor.
And her brilliance went far beyond anything you or I could imagine.
