CNN and other reliable news sources reported the leaflets were distributed by masked men outside a main synagogue, but said it wasn't clear who was responsible.
So, they fulfilled their duty responsibly to report worrying events, but didn't blame anyone in particular without evidence.
The BBC basically ignored the leaflets, so those who have it as their main source were not provided with a good service. A vacuum, when the news is out there, is more likely to lead to conspiracy theories than trusting us with facts and a sober assessment of possibilities.
The Daily Shame is not a serious news outlet.
