Pearson points out that women are still receiving preferential treatment in the justice system; for example, one study found that men were 11 percent more likely to be incarcerated than women for violent crime. Perhaps, this is why people think women are less violent than they are. They do not receive much, if any punishment, and thus, are seen as innocent. It also shows up in the stats as a lesser crime or none at all.

Women do not get the help they need in order to change their behavior before it escalates. In addition, to pretend that women are not capable of real violence is to take away their autonomy and deny that they are capable of the full range of human behavior and emotions, and how sexist is that?
