Oh yeah...by "specific purpose" I mean line of duty.
I'm not aware of police officer regulations, but military wise, there are procedural situations where the weapon is ready to fire whether the threat is present or not. Clearning rooms, convoy situations, show of force, etc. As limited as they are....I've had a weapon out, with no immediate intention to fire and no immediate threat - thought definate cause to have it out (guarding undesirables, etc)
With all due respect, if you are legally drawing your weapon in any capacity, that is EXACTLY what HAS happened.
If you are not justified in shooting to stop a deadly force threat, you are not justified in drawing/shooting AT ALL.
