Question of the Day - Double Standard?

The Knowles-Carter family has recently made headlines when a video emerged that showed Solange Knowles violently attacking her brother-in-law Jay Z. Jokes were said and meme were made, but this is a bigger issue than what we may let on. In some cases women are in fact the aggressors and not the men; however, women often times aren't scrutinized or punished as much as men. So this raises an important question, is there a double standard in domestic violence when it comes to women versus men?
