Are D-Notices being used by the government to hide facts from the public?

 
Just in case you don't know or have never heard of it, a  D-Notice is something the Government uses to silence the press from reporting things the government does not want the public to know about! there is so much more to add to this page, but for now just this From Wiki below,  In the UK, the original D-notice system was introduced in 1912 and run as a voluntary system by a joint committee headed by an Assistant Secretary of the War Office and a representative of the Press Association. Any D-notices are only advisory requests and are not legally enforceable; hence, news editors can choose not to abide by them. However, they are generally complied with by the media.

In 1971, all existing D-notices were cancelled and replaced by standing D-notices, which gave general guidance on what might be published and what was discouraged; and what would require further advice from the secretary of the Defence, Press and Broadcasting Advisory Committee (DPBAC). In 1993, the notices were renamed DA-notices (Defence Advisory Notices).

One of the recommendations resulting from the 2015 review of the D-notice system included the renaming of the system to the Defence and Security Media Advisory (DSMA) Committee. This name reflected better the longstanding inclusion of the work of the intelligence agencies. In 2017, the notices were reworded and then reorganized into the following categories:

• DSMA-Notice 01: Military Operations, Plans & Capabilities
• DSMA-Notice 02: Nuclear and Non-Nuclear Weapon Systems and Equipment
• DSMA-Notice 03: Military Counter-Terrorist Forces, Special Forces and Intelligence Agency Operations, Activities and Communication Methods and Techniques
• DSMA-Notice 04: Physical Property and Assets
• DSMA-Notice 05: Personnel and their Families who work in Sensitive Positions

According to an article in Defence Viewpoints, between 1997 and 2008 there were "30 occasions where the committee secretary has written to specific editors when a breach in the D-Notice guidelines is judged to have occurred" But how often is this used and what for? When you look at the media some stories are not covered at all, For example Christian Churches being attacked in the UK, below Christians murdered by Muslims in Africa.

    And 

Man's throat slashed by Migrant gang in Birmingham, there are so many things that are not appearing in the news, there is a video of a Christian Church being attacked online with all of the patrons screaming inside as a gang of men with knives try to get in! The news should be for everyone and everything should be reported; it should not be selective.
