There is no way round it because the apparently absurd or trivial can turn out to be something much more serious.
However, I do sympathise with the requirement to investigate every complaint about a tweet which has caused offence to someone. The line between offensiveness and potential criminality may be fine but most of us know it when we see it.
A case in point is the tweet by Councillor Rhiannon Spear who was moved by the Eurovision Song Contest to tell the world that Scotland “hates the UK”. Complaints have led to the inevitable “Police probe…” headlines.
Yet what is there to investigate? The tweet may be stupid and bigoted but if every stupid and bigoted utterance in Scotland was investigated by the police, they would not have much time for anyone else. Stupidity is not the same as criminality.
Ms Spear is the SNP’s national women’s convener and in these circles “hating the UK” is more likely to be seen as a credential than an offence; hence her rise to eminence.
The role in which Ms Spear is laughably inappropriate is as chair of Glasgow’s City Council’s education, skills and early years committee. In a city where prejudice is all too common, anyone who even uses the word “hate” should be kept at a safe distance from young minds.
This is not a job for the police or the SNP but for her fellow councillors of all parties. Ms Spear should be found another billet.
