When a policeman said “You’re under arrest” to John Lewis, a lifetime of absorbed taboos against any kind of trouble with the law quickened into terror. He tried to blot out everything but his rules as the police frisked, cuffed, and marched him to the paddy wagon.

They had held steady through the worst, he believed, and by the highest standards they knew there was no doubt that they had been in the right.
