{how could they do it, how could they}

“Atticus–” said Jem bleakly.
He turned in the doorway. “What, son?”
“How could they do it, how could they?”
“I don’t know, but they did it. They’ve done it before and they did it tonight and they’ll do it again and when they do it — seems that only children weep.”

— To Kill A Mockingbird, by Harper Lee
