.. it is easy and not at all confusing because two such instances relate to two [or more] different people, or persons, and that the exhibits in question, would have been seized or found on different occasions, and not relate in the same instance, to the same item. Not only 'this' / 'that', but each item would be numbered in sequential order, demonstrating which item of evidential value were 'seized' or 'found by that person' - but this did not happen in this particular police investigation...
Each exhibit 'seized', 'found' or 'recovered' at a crime scene should be placed in a plastic exhibit bag [before it is taken away to the police station] , [or, as the case may be], for sending to a lab' to be `scientifically examined` by 'a variety of so called experts' ...
Attached to this plastic exhibits bag, should be an exhibit label, bearing 'the signature of the police officer', who 'first took possession ot the item' [or 'who saw it in the first instance', or as the case may be, 'who referred to its existence before anyone else']. The 'signature of the finder', should 'be on the exhibit label', accompanied by 'a number',(1, 2, 3, 4, etc) to 'confirm the order in which item', was 'taken'. Upon 'arrival at the designated police station', each item has to 'be manually entered into an official documant', known as 'the property other than found register', after which 'the items are transported to a property store at that establishment' - there is a ['separate'] 'property store register' belonging to 'the property store', in which 'everything that is placed into storage there', has 'to be recorded by inclusion of its exhibit recerence', the 'signature of the police officer', of 'the person' who is 'depositting' any number of 'items', there, and 'the date' and 'time', that 'the item's in question', were 'placed into storage', in 'there' . In addition to this, 'there is a police officer' who 'is solely responsible' for controlling 'what is put into storage', 'inside the property store', who is 'duty bound to countersign', 'each entry' in 'the property store register', alongside the 'signature of the depositivees'[adding 'date' and 'time' , against 'his', or 'her signature'[these measures are necessary to prevent 'a police officer' getting access to items of evidential value' and 'tampering', or 'exchanging one item' , for 'another', or from 'deliberately contaminating it' , or ''them' ...
It is 'significant', in this case, that 'no such police documentation', 'confirming these protocols', were 'strictly adhered to', in 'the case' brought, against 'Jeremy Bamber'
