The BBC seem to have deliberately omitted the word anti from their front page lead into this report http://www.bbc.co.uk/news/world-us-canada-39612785
The lead says that Trump demonstrations turn violent, surely it was anti Trump demonstrations that turned violent but all news concerning President Donald Trump has to be reported through the BBC's anti Trump narrative.
The actual report runs:
'At least 21 people have been arrested in Berkeley, California, following clashes between opponents and supporters of US President Donald Trump.
Several people were injured when fighting broke out on a day of nationwide marches calling on the president to release his tax returns.'
It would be interesting to know the relevant numbers of supporters and opponents of President Donald Trump who were arrested but as the BBC don't give figures I think we can assume that many more opponents than supporters were arrested.
