CNN anchor on Ferguson: 'Why not, perhaps, use water cannons?'

Oh dear. CNN anchor Rosemary Church, asking a live guest about police response to mostly black protesters in Ferguson, MO:

"Talk to us about what police are saying to you. Why they are using this strategy? Why the use of tear gas, stun grenades? Why not perhaps use water cannons?"

Co-anchor Errol Barnett's facial expression, which suggests an unspoken reaction, has become an internet meme.
