Yes, there is such a thing as a dumb question and it is usually asked by a dumb lawyer...
“Were you alone or by yourself?”
“Was it you or your brother who was killed?”
“Without saying anything, tell the jury what you did next.”
“Was that the same nose you broke as a child?”
“Now, doctor, isn’t it true that when a person dies in his sleep, he doesn’t know about it until the next morning?”
