I don't argue for use of violence and therefore I don't need to provide any justification for it. It's people who suggest laws and regulations as solutions need to prove why they can do that. Without a proof, it's just bullying and mob rule.
Why is burden of proof is not on me? Because I don't stop the discussion by taking out a gun. If you don't agree with me you are always able to go away, or tell everybody to not talk to me because I'm not nice to others. No one kills anyone, everybody is free to agree to disagree. But whenever somebody gets angry that I disagree and takes out weapons, then it's up to him to explain why he is doing that.
Because you're arguing that representatives of the government's executive branch should not be able to use force to defend themselves when threatened with force. That violates the golden rule, which, being core to many moralities, places the burden of proof on you.
Don't you think, the representatives and their supporters need to justify their use of violence first? If not, then I can also end this discussion by killing you without justification.
Example 1. Everyone thinks the Earth is flat, but I don't think so. Since everyone's senses indicate that it is flat and my idea is not self-evident, it is me who must provide sensual evidence. E.g. by showing that the horizon is limited and ships go under.
Example 2. Many people think the god exists, but senses do not provide any common (objective) perception. More than that, if you show them that by behaving badly you don't get mysteriously evaporated, it's now their job to prove how and why the god exists.
In other words, me and other people see a lot of evidence that some people kill other people, but we do not see a solid reason why some have a right to do so, while others do not. Then someone comes and says "it is democracy". Very well, but it is very far from being satisfactory answer and it has even more moral questions. E.g. how sudden increase of 50% audience by 1 person reverts their morality? Or what happens if older voters died and new were born? What are the "borders" within which you can use democracy, but outside - it's another jurisdiction? All of this stuff is 100% imaginary and outside of realm of sensual evidence. So it's your job to prove that these imaginary concepts have any ground. Quarks are imaginary, we cannot feel them directly or indirectly. So it's up to physicists to prove to anyone else that this imaginary model is useful at organizing all their real sensual knowledge in a coherent manner. And if they derive from quark theory that they can kill people - they have to prove it first.

No you can't, because I have not acted violently against you.
The state will not act violently toward a citizen in excess of the violence that citizen has displayed toward it: the government will not kill you unless you resist with deadly force its lesser efforts at punishment.
You must also keep in mind that violence need not be physical. (If you ignore non-physical violence; e.g. pollution or speeding or libel; you will have a very undesirable society in which to live.) Laws (purportedly; actuality may be less ideal) exist to prevent what society at large has deemed to be some form of violent intrusion on their safety/privacy/liberty/etc. Therefore, if you have broken a (just) law against some person, you have committed some form of violence against them, and violence (generally in the form of moving you from your home to a prison cell) is justified in their defense.
