Let’s settle an argument

It’s 8pm. You’re in your driveway with your back to your house. You hear the stun gun sound followed by your wife screaming in one of the most blood-curdling, terrified ways you’ve ever heard. You see one of them running towards the middle of the street with her. Another guy is running towards you with a knife and a taser. Someone rushes up behind you and smacks you at the base of your skull with a baseball bat. <br><br>You have a bulletproof vest on. <br><br>What’s your plan?
