So she IS actually a EMT/Dispatcher who called (dispatched) an ambulance. Why would she be arrested? What kind of care can an EMT give for a breathing problem without equipment?
The inhaler in her purse?
Most asthmatics do carry inhalers and it would have been wise to ask if anyone else in the place had one. Even holding a person's arms above their head eases breathing distress sometimes. It's sad the EMT didn't do anything or show concern. She could have been prepared to do rescue breathing or CPR prior to the ambulance arriving. Even though she was a dispatcher, she had been trained.
Maybe she is one of those who thinks the law is stupid and doesn't like being forced to act. Or she just doesn't give a shit. She clearly isn't compassionate. Most people would at least talk to the woman and try to calm her. Panic seems to make asthma attacks worse. I know, I've had them.
