I don't know about UT but here in MO we have a law that addresses your question.
Is the above excerpt "defining" brandishing? Subjective? Open to interpretation? Sure. Depends on how the observer defines brandishing I guess. Is pointing a gun at me a crime? Depends on the circumstances. This is what cops and prosecutors are supposed to figure out.
Some folks consider the folks back in 67 were brandishing their firearms, no big deal, I disagree. Some folks consider the folks in WA, more recently, were brandishing their firearms, again, no big deal, I disagree. I know what a threat to me and mine is when I see it. Brandishing is a completely subjective term. This is why I advocate that actual, quantifiable, harm done is what must be addressed by LE and judges. Maybe could've, or maybe would've, gives too much power to the state to decide what you are I should've believed.
