Stepping into a lion's enclosure at a zoo is a really, really bad risk management decision ...
Not excusing what she did, but it does appear that she climbed over the barrier that keeps humans from falling into the ravine; not past the ravine that would have turned her into a tasty snack.
If I want attention, this would not be the way I would do.....some folks....and yes she should be nominated for the Darwins of 2019.
