I had accidental lock screen 921 call once. I panicked and hung up. They immediately called me back and I explained what happened. The dispatcher then asked If I was under distress and answering truthfully. It threw me off and there was a long dramatic pause. She asked me if I’m sure and I repeated yes and the dispatcher sent out a cop to check up anyway. I felt bad for wasting their time, but it was good of the dispatcher to even think to ask that.
