Well let's see we have a M/A agreement w/ Kearny so we respond, 2 out of 10 times they may answer the radio. Plus if there is no communications on scene with the Police we consider it an unsafe scene. Case in point one of our Volunteer crews where almost stabbed by an EDP that there Police did not respond to.
So we give it a good try, Myself I have zero tolerance and have no problems turning the ambulance around I want to go home to my Kid and my dog and yeah the wife. Plus everything above is well documented with our Police and by IR reports, Just think all they need to do is turn up the volume.
