You forgot what was being discussed. You said you had no reason to doubt. Yes, you do. The article you provided was apparently written by a young and stupid child that could do little more than copy the work of others. That is alone is sufficient reason to doubt.
That journalistic triumph The Daily Mail, for instance, actually did a little homework and includes thr video of the police interaction. The rag you quoted was too lazy, hence should not be taken on their word as credible.
British police officers have been branded as the 'Stasi of East Germany' after they arrested a man last night over a social media post.

The joke article you propped up got bitch slapped by the Daily Mail. Let that sink in.
Eta: your article was so poorly done that it didn't even get the town where the arrest occurred. That's about as lame as you get for reporting.
