Whoops! Totally didn't mean to don a ski mask, beat and threaten you.

The Egyptian military apologized for unintentionally using "truncheons and electric shock batons against late-night protesters in Tahrir Square." Someone explain to me how this can be unintentional:

Salma Said was asleep in a tent when it began to fall down on top of her. Outside people were screaming, and she emerged to see people being beaten by soldiers and armed plainclothes security officers wearing masks.

“They had their faces covered like criminals,” she said, “They only showed their eyes.”

“One of the officers threatened to shoot us and said he was going to set our tent on fire,” she said.

Did that officer have Tourette's Syndrome?  How else can you accidentally threaten to set someone's tent on fire?  I'm most curious.
