Officiant fires gun to welcome bride, shoots grandson — and wedding goes on

That is definitely not an appropriate way to start a wedding ceremony. Depending on the severity of the injury, this could legally be considered a criminal act. If the grandchild has permanently suffered a physical or emotional trauma, further investigation or legal action could be taken against the officiant. In any case, the wedding should not continue as if nothing has happened, and the couple, family, and guests should immediately take appropriate medical and legal action in response to the incident.
