I hear ya. But again, I go back to the original call being a medical dispatch. If you call 911 and say "I found someone who's covered in blood" dispatch will send the entire calvary. If you call and say "my co-worker collapsed, he might be having a heart attack" they are sending EMT.
Obviously there's a huge gray area between those two extreme examples and dispatchers are trained specifically to ask simple questions to triage every call. They know that people might be upset usually when they call 911 and might give incomplete or incorrect details so they are trained to ask questions multiple times in order to understand what is going on, all the while dispatching the correct services to the location.
If the 911 contains details of the crime like "please help! i came in this morning, i saw Joe Suspect leaving and now my coworker is in a pool of blood, looks like shooting/stabbing!" and they sent EMTs only then that dispatcher is probably already pulled and suspended and shortly will be looking for new employment.
IMO
