Chances are the prosecutor can manipulate that evidence to look good to the judge/jury much better than the defense lawyer can make a counter-argument for why it cannot be used in court. At least that has been the trend with stingrays and other bleeding-edge surveillance technology that is poorly understood by judges.

The prosecutors are backed by government and FBI resources (including technical expertise). Your average defense lawyer isn't. Hell, the FBI was even teaching prosecutors and the police to say that using a stingray was under NDA with the company providing it and therefore they couldn't talk much about using it in court (but still benefited from the gathered evidence).

This was in Germany, so I highly doubt the FBI was involved. Also there isn’t really a jury system.

I don't think it's the judges who are poorly understanding the technology...

I'm not able to edit my health kit data. perhaps some apps that integrate can do it, but the ones I use do not and I'm not able to in the health app itself.

You can absolutely edit your health data.

I can definitely add and delete health data, but on iOS 11 I cannot edit a device-provided value. Not for heart rate and steps anyway.

No I can't. I tried. Did you not read my comment?
