I am not a Twitter person but these two tweets appeared earlier today:
Update dog that was on the airfield at AKL_Airport has now been caught
7:30 AM - 17 Mar 2017
Unfortunately an Aviation Security dog was shot this morn @AKL_Airport staff had tried for 3 hours to catch it our thoughts are with handler
8:35 AM - 17 Mar 2017
It looks to be a major screw up, or an 'alternative fact', to say that the dog had been caught, as posted at 7.30 am.
An hour later the true version appeared. I would not want to be person responsible for the 7.30 tweet. Even Sean Spicer would not try that one!
