What does scout mean when she says well it'd be sort of like shootin' a mockingbird wouldn't it?

She said this because, killing a mockingbird is a sin because they don't harm your crops or flowers or anything they just sit and sing their heart out for us. Well prosocuting Arthur Radley (Boo Radley) is like this. It would be completely wrong to prosocute him for something like that when he is just a lonely, quite and seldome seen man.
