Had a situation years ago when I was an EMT and still in the field. We were dispatched to what sounds like a very similar situation as what you described Millcreek... Family called because family member is threatening claims to have a plan,.etc... Of course we get there with LE and it's deny deny deny. We were all on scene for close to an hour trying to convince her to come with us to get evaluated... Finally we're packing up leave, she's refused to go with us, and we're heading out the door. I stopped in the atrium at the front door to tie my boot, when I hear clear as day, from the back of the house, "I can't believe you called 911, maybe I really *should* just drink the bleach and get it over with!!!"
Whoops........
Get on the radio to my partner, "Don't let those deputies leave. We're going to need them..."
Walk back towards the back of the house, deputies in tow, "Ma'am, now you are most definitely going to need to come with us tonight."
The temper tantrum she threw was *epic*.
