That's not enough or even the right kind of premeditation, especially not for a police officer who may routinely draw as a matter of precaution.
We civilians are in pretty much the spot your CCW instructor said. Brandishing is (usually) asking for trouble.
-- The same rules apply to cops. --
No, not quite, not when it comes to brandishing, and not even when it comes to using deadly force.
See cop who drew leather in the pool party incident. Caught a bunch of crap for it, but no brandishing charge. If you did that, you'd be hit with a brandishing charge.
Then what you’re saying is part of the problem. If police are above the law then they’re going to act like it, aren’t they?
Don’t be surprised if you one day come face to face with one of these people who decides that you’re not properly debasing yourself in the presence of their authority. I hope you survive the encounter to tell us about it.
