That is impossible to accomplish...its human nature to be violent...but I rather be knifed than shot if we confront violence!
First, by accepting something as impossible, you have already failed in any hope to accomplish the task.
Second, it's in nature (not human nature) to be violent. There are no creatures which are not capable of violence. Despite the rhetoric of some, animals do kill out of pleasure.
Third, why would you rather be knifed? The most capable serial murderers and string killers in history have used knives, thus proving their effectiveness as greater than a firearm. Your chances are actually equal in survivability, as the location of the injury is more important than the method of injury.
I don't disagree that violence is bad, but I prefer to approach it in the matter that Ryat does.
