Dr EMILY HENDERSON: Lock people up. It is very, very easy to think, let's throw away the key. It is very, very easy to think "An eye for an eye and a tooth for a tooth." It is very, very easy to think, "Let's get vindictive, let's do something knee-jerk, let's do something hard because it makes us feel good." Do you know how long it makes us feel good? About 30 seconds, because the problem is it doesn't work. It would be fine, if this actually effected some change.
