(25 Seconds into video)
This video is interesting because one, it does not involve a human attacker, but a dog, two because the officer sees the charge but waits while pointing his finger.
The dog is appears to be at full speed and close to 6 feet away before the officer reaches for his weapon. The officer may or may not have been able to actually get his weapon out and delivers a kick. I do not know if the officer was trying to restrain from drawing his weapon or unable to extract it from his holster quick enough.
BUT, how can we use this footage to see the realities of closing distance. I know dogs can move quicker and are smaller targets but is this a valuable tool to look at for these purposes?
