Extremely good question. I assume that until the time the police located and took possession of the papers, they weren't in any way aware of them existing? ie, they did not locate them, disregard them, and then realise the significance and come back months later with a warrant?
I have said this many times before and maybe some people find it inappropriate for suggestions to be made as regards LL's state of mind and psyche but to my mind, LL has probably got a sophisticated slippery thinking system, compartmentalising, and denial mechanisms applied internally to her own self and her own ego, never mind how she interacts with others.
It is possible that in her mind, the papers just 'came home' with her (all by themselves, uninvited) a situation in which she had no input, agency, or control. Since they weren't meant to be there, and she didn't do it, they didn't exist in reality in plastic bags under her bed, but in some 'other' space that she couldn't deal with thinking about and ignored. So they sort of existed only in a very partitioned off part of her that isn't freely accessible to all of her. Ergo most of the time, there is nothing that needs to be destroyed.
When she did think about it more consciously, she literally lost her mind, couldn't cope, wrote despairing post it notes in a high level of agitation and distress. Notably, even then still couldn't bring herself to face up to destroying them which would have taken very conscious present moment action and agency over herself, so she stuffed them back under the bed again. A form of internal hide and seek with herself, never mind the police. I think the proof of this argument is that she hadn't destroyed them. Anyone would have.
