No charge will be filed. That's silly. Various definitions of brandishing follow:
Brandishing - display or exhibition of a dangerous weapon, with the intent to use, intimidate, or threaten another person without justification.
Note “without justification”.
“To wave or flourish in a menacing, defiant, or excited way.”
Note “wave” and “excited way”.
“to shake or wave (something, such as a weapon) menacingly.”
Note “Menacingly”.
“Brandishing is one thing, but aiming is the ultimate brandishing,”
Note “aiming it”.
“to draw or exhibit the weapon in a threatening manner, or to use it in a fight, other than in self-defense.”
Note “threatening manner” and “other than in self-defense”.
In this state self defense is treated as unjustified.
