In this situation, our dispatch would send a police unit to the scene. Thats just doing a welfare check, and no need for EMS to even be involved. Your dispatch needs to look at their protocols a little bit better, they may need worked on. Those are actualy some dangerous situations, where PD should be the ones to check on. A suicidal person, if they want to do it, will and will take you with them if they have to. The little old lady could be DRT, and it could be a possible crime scene.
