Sorry, I found no other way of contacting the site about an easy exlanation I found for one of those contradictions, I think I have the explanation...

*PW:AA case 5 spoiler*

Differing Levels of Security
The security room shown in case 5 requires an ID card and code, and has fingerprint identification in place, all for cases that have already been solved. The evidence room at Criminal Affairs has virtually no security. (-Mikker)

Well, that security gap is because, at Criminal Affairs, you must take evidence in and out too much and too fast. I mean, if she asks for that evidence and you had to find your lost ID card and remember you code before getting it to her? That would mean a whole lot of whipping...

I didn't even think it was contradictory because that's what I believed right when I first saw it...

It says they're not accepting new contradictions or explanations, and also, this is the place:
