“Way safer than sending a nameless courier.”
Except they got caught at it, so it wasn’t very safe. I’d have sent a messenger/courier....
A courier who is low on the food chain and unprotected, might be worse than “caught.” Not to mention he is always open to a higher bidder, as he has no personal stake.
Nor were Clinton and Lynch caught at anything but running into each other. An appearance of impropriety, rather than an impropriety.
