I have a few “Q”s of my own about this one.
Q: If the guy really had a warrant on him, why didn’t the same police officers who arrested him notice that when they pulled him over a couple days before?
Q: Why would the same officers who had a recent verbal altercation with the suspect be the ones who went to serve the warrant on him?
Q: Why would a K-9 be brought along on an arrest warrant service that has nothing to do with narcotics?
Q: Why would the suspect be running to the rear of the domicile if there were no rear doors or windows in the residence?
Q: Would a police dog bite the suspect in the crotch if it had not been trained to bite that area, possibly on command?
Q: Should a police officer who would train a police dog to bite citizens in the crotch be wearing a badge?
Why would the suspect be running to the rear of the domicile if there were no rear doors or windows in the residence?
To get a gun perhaps?
The rest are speculative (ie you don’t know if it was trained to bite on the crotch, they may not have checked for a warrant, etc)
