If one is capable of yelling and screaming, one is not having any problems breathing.
Unlikely that Jaramillo was experiencing an allergy attack.
Breathing is periodic. Not breathing is death. Letting out a scream because of the difficulty of not breathing periodically is perfectly reasonable.
Unless you're trying to justify murder. Is that what you're playing word games to achieve? Ever witness someone ask for help during an asthma attack, or are you just entirely ignorant and indifferent to life threatening situations created by police intervention?
