The story originally said
"The first thing they said was, ‘Some of your tweets have been brought to our attention.’ When they brought out the screengrabs of the statement, I said, ‘Really?
“They said, ‘Yeah, we just have to speak to you. You’ve not said anything hateful, there isn’t a crime here.’
“I said: ‘So why are you here?’ They said, ‘Because we need to speak to you to ascertain what your thinking was behind making your statement.’"
It carefully said 'brought to our attention' not 'complained about'.
And clearly not subject of an investigation.
So nothing that contradicts the story at all, but I wonder why it was removed - perhaps the officer who didn't want to be quoted has threatened something? (Just speculating??)
