In real world application, thats probably what I would have used in this situation when it denegrated into resisting arrest. All it does is burn the eyes and make breathing a little difficult (when it works.) It injures nobody.
By burn I mean irritate considerably.
The pepper spray would be less of a concern for a pregnant woman also.
No matter what is done to effect the arrest, it will be perceived as being too much. Most decisions made by Police officers aren't very popular
As long as policy and the law are complied with, and reasonable steps are taken to minimize risk to all parties, legal exposure to the officer and the city is
minimized.
I would hope at least one of the officers had a vehicle mounted camera that recorded the incident. Those can take a lot of steam out of unfounded complaints
