Leaders and sunglasses?

If there is something I don't like with Head of States or Political leaders are those who wear sunglasses when addressing crowd. This makes me uneasy and conjures up Orwellian fears in me.

I was looking at the new Egyptian strongman al-Sisi yesterday, hidding behind his shades and couldn't prevent myself from associating the man with Qaddafi, Jackie Kennedy or General Jaruzelski.

It must be something I hold against political figures, because I've always been a Roy Orbisson fan who in turn, was another sunglasses addict!
