From a dispatch and officer safety standpoint I completely DISagree with the quoted statement.
There is safety in numbers. There is no way to predict how suspects will react to the arrival of police, and even less way to anticipate how they will act regarding the number of officers who show up.
If they are inclined to fight the police due to their peers being around, then more officers should be sent.
