again when a gun is in play if you are attacked regardless of what it is and it can incapacitate you and you being the one with the gun have the right to use your weapon in self-defense
That's not accurate nor will it enter the defense.
My bet is this guy pleads down.
There is no self-defense in this case.
From my criminal justice experience, it's very accurate
What happens if you are carrying a gun and someone uses mace on you and they take your gun shoot you and others wouldn't killing that person be in self-defense before he used the mace?
Nope, unfortunately we are not mind readers, so a pre-emptive strike is not allowed. The only thing a person can be trained in, uhh is how to use a person's body language and threatening speak in order to adjust accordingly to a possible threat, otherwise to position oneself out of the danger zone if the person decides to make a move based on these things as a lead up to the move. Now, another thing is that if a person is making threatening body language or threats to your life verbally, and maybe they are armed or not, then you could get the drop on them first by drawing your weapon, and aggressively ordering the person to the ground hands behind the back until help arrives. If the person doesn't comply, then just keep your weapon drawn in order to stop any further advancements of the person on you.
