Not being a legal expert, I can’t tell where the boundary is between enabling legitimate police work and giving (accidentally or deliberately) the police the power to plant fake evidence, the latter being what some of this sounds like. But, I’m not a legal expert, and “sounds like” is a way to make very large mistakes when looking outside of one’s own domain of expertise like I’m doing here.
(Also doesn’t help that I hear about stories like this from people who don’t like them, so I get a potentially biased first impression).
