It’s convoluted because they needed a parallel investigation to use in court.

1. Use illegal means you don’t want to admit in court.

2. Locate suspect

3. Manufacture a plausible excuse that suspect was found.

4. Use that in court

It’s not a hypothetical, it’s fucking procedure

No one knows everything, I’d encourage you to ask questions next time.

Quick edit:

That’s actually the second time in a row you did that, if I stop replying, it’s because I gave up on helping you and won’t see anymore replies in the future
