What initiates violence, "offensive force" is a person(s).
A gun is an inanimate object and gathers dust until a person uses it. A sword is an inanimate object. A lead filled dildo is an inanimate object (do they even have those? )
The guy who starts shooting at you could be a cop or a thug, but I repeat myself.
He's shooting at you, because he has made an inanimate object into a weapon of offensive force.
Putting competent people in an incompetent system to carry out contradictory things will not change the nature of what is really happening.
Truly peaceful people would not use guns to disarm peaceful people. A pacifist is a statistic waiting to be tallied.
