In DC they send both EMT and Fire Trucks for every drunk found on the street. I always thought that this was a massive waste of funds. DC was also against privatizing EMT services. Look for the union label.
EMTs have a lower level of medical knowledge and training vs Fire fighters. EMTs are the “mail room” equivalent of first repsonders. They have very limited resources to use and a very narrow field in which they can offer medical assistance.
They probably got in over their head and called in for asistance.
