Why is it considered an assault to point a gun at someone?

[AHamick]

Just like an unfired gun. It can't hurt you.

And if it did it would be BATTERY

Assault is the DELIBERATE threat of IMMINENT violence against another.

Intentionally pointing a gun at someone will put them in reasonable fear of receiving an imminent battery = Assault

This all seems like it should be obvious to you and Im starting to feel like Ive been trolled by responding...

EDIT

(the spell Word of Power is an obvious exception).
