...scoutsabout...that's one thing I don't miss for sure...that damned continuum of force...
I totally agree. In exploring all the technicalities, we tend to forget the big picture. Civilians are not required to use deadly force, though we are authorized under certain circumstances. When the "big three" exist, we can be afforded some protection if we choose to act.
Apart from all the EOF/COF crap, I think the decision to assist an LEO in distress is pretty simple on the surface. If the LEO is fighting for control of his own weapons, then it can safely be assumed that the subject is displaying the three factors that validate a deadly force responce. The LEO would be authorized to use deadly force in that situation, and so would anyone assisting the LEO.
Ability - we can assume the perp knows how to use the LEO's weapons. Especially a Glock.
Opportunity - yes, the perp has his hands close enough to acquire and use the LEO's weapons.
Jeopardy - yes, he is endangering the LEO's life.
If the LEO is struggling, I would offer to help and provide assistance only with permission. If the LEO is clearly losing or has lost the struggle, and the perp has a weapon... then I kind of wonder if I could empty my gun into the perp before he hit the ground.
In all reality, this is a tough question... but thinking about these scenarios will invariably help us be prepared for the worst.
The real problem with these scenarios is the gray area. The LEO is still struggling, but could win or lose the fight at any moment. If the LEO has lost the fight, it is a much clearer decision. Would we open fire on a perp that was apparently about to execute an LEO with his own weapon? That is a clearer decision, in my mind.
At any rate... whether you are willing to risk your life for the good of humanity, that is the real question at hand. For those of us who have already done it, the choice is probably clearer still.
Better to die for something than to live for nothing.
***wait a minute*** we're getting too embroiled in the possibilities here. I just took another look at the OP's original question. He affirmed in the question that the perp
had already gotten ahold of the LEO's gun... so the choice is very clear, in my mind.
FIRE AWAY. Scream commands at the perp and assurances to the LEO to hopefully aid the LEO, any witnesses, and responding LEO's in identifying you as a good samaritan.
