@911 is an EMERGENCY number
"In the US, 911 is a number for emergency services (police, fire, ambulance, wilderness rescue, etc) in case of an actual emergency. Being shorted $4 is not a life or death matter."
911 is not only for life and death matters. The dispatcher told her an officer was on the way, so the dispatcher thought it was worth forwarding even if the officers didn't want to respond to it. Should the dispatcher be arrested too?
"She should have called a non-emergency number for her local police department. She wasn't arrested for contacting the police. She was arrested for misusing the emergency contact system for a non-emergency situation. There is a great deal of difference between settling a theft or fraud dispute and someone's life being in imminent danger."
She's not a lawyer, and saying an officer is on the way confirms to her that she is right to call 911. If the dispatcher thought she should call the local police for that, why didn't she forward her to the local police, or tell her the number or at the very least say so?
As to whether this is a police matter, well if it wasn't Micky D's but a scam artist on the street that pulled a bait and switch would you expect her to call 911? Micky D's are not special you know, they don't have special corporate rights.
To me if the police had time to arrest her for calling 911, they had enough to deal with this matter. Getting all high and mighty about which crimes they will and won't pursue just smacks of inflated self egos getting in the way of the job.
