Peacemakers do practice peace, BUT when peace does not work sometimes violence is the only option. Consider World War II for example Peace was tried and it turned to violence and death, but there is no telling how much more death there would have been if `good men did not stand up and use violence. Another example suppose someone is accused of murder the sespect is located well the police always hope that the person wil go into custody without a fight so that they do not have to use violence to stop the threat, BUT if the suspect insist on being a threat to them or others they will and should use lethal force to stop the threat. Same thing with other violent crimes some of the best Christians I know own or have owned guns (one particular woman I am thinking about is deceased of natural causes last year.) They (the people in question are some of the LAST people I would expect to so much as raise their voice in anger, BUT if they felt that they or the people they were with were in danger of death or great bodily harm or if they caught someone harming the same I can also promise you that if they had their firearm on them ( and I know more than one of them to carry they would use violence to stop that threat
