Pie thrown at Murdoch

Rupert Murdoch was attacked by a protestor wielding a shaving foam pie as he gave evidence at the Culture Media and Sport committee on phone-hacking.
His wife Wendi Deng was quick to defend her husband.

Leaving the rest of us to wonder:

Or was it all planned as a Murdoch publicity conspiracy to divert the headlines away from his non-admissions of any guilt or responsibility and onto some kook who got bitchslapped by Mrs Murdoch?
