In this case, some of his cases (and there are many articles, and they are worth a read) appear to be for good reason, and rthere will be some substance to some of them; but we don't know - which is partly why he rails against them.

Dig deeper using other sources, before coming to premature judgements. These stories are designed, DailyFail-style, to tug at your heartstrings. It's also worth knowing that The Daily Telegraph has always been the UK Rightwing broadsheet, but has since its change of ownership in recent years, turned more to Daily Mail-like reporting and sensationalism. IT has also taken a hard turn to the neoliberal Far-Right (think Brexit), and so you should take its stories with as much caution as perhaps the 'Washington Times', and worse than Murdoch's WSJ. It's not yet as bad as Beitbart, as it still advertises to octogenarian Colonels in Tunbridge Wells, but that may change.
