In a segment about clashes between police and protesters in Ferguson Monday night, CNN International anchor Rosemary Church asks: "Why not, perhaps, use water cannons?"
And her co-anchor Errol Barnett's response:
"Wait, what....?"

"Did that just happen?"

"Is this real life?"

Twitter users were swift in reminding Church about the history of using water cannons to quell civil rights protesters in America:
I just wanted you to see what a water cannon was. Perhaps you would like to be in front of one yourself. @rosemaryCNN
She said why not use a 'water cannon' like they were having a Super Soaker war. You mean this @rosemaryCNN?
.@rosemaryCNN this is why they dont use a water cannon RT @CarelessRichy: "Why not perhaps use a water cannon?" @CNN
