Why has the reference link to Hydra and Minerva been taken off without this reference few people are going to understand what the systems are for and what part they play in NPIA training I personally added the sections Serious Crime Analysis Crime Operational Suppport National Missing Persons Bureau Traing and the technology section However when it comes to referencing my work or proividing links I have been prevented from doing so and the page is put back to the sections I originally added  Can this page not be added to what is wrong with a reference explaining what minerva and hydra are indeed what was wrong with a link to the Metropolitan Police Crime Academy one of the most important crime fighting academies in the UK and which has close links and operational ties with the NPIA  It seems to me that petty moderating is destroying any attempt to even reference or explain such points in any detail
