"Can you state exactly what your threat model is?"

The threat model is that police and prosecutors need to find someone guilty. If you watch the video to the end, the lawyer explains exactly how even a genuienly completely innocent person might be convicted of a crime because they were able to use "some" evidence to show that you maybe were near the crime scene. They don't need definitive proof - they just need enough to sway the jury. And if you take that into consideration, then giving law enforcement any info about you can only ever work to your disadvantage.
