Missouri's state Senate passed a "stand your ground" law on Friday, sending the bill to the state's House, where it will likely pass. The bill, which now has a veto-proof majority, is likely to become the first "stand your ground" law to pass since the 2012 killing of Trayvon Martin—which famously initiated conversations about such laws existing in Florida. The statute allows a person to use deadly force with no duty to retreat in the face of a perceived threat.
