She got drunk, had a moment of stupidity, it was captured on camera. No one died! This is a typical Saturday night scene in many a town in the UK.
I don't condone it, but the faculty should really look at themselves before they chastise this bird. Half of them are probably avoiding tax, shagging their wife's sister, etc.
Fire her for being shit at her job, not for having a moment of madness, whilst drunk, in her free time.
