I don't know, but it seems quite likely, unfortunately. There were quite a few other cases when fake evidence was planted by police.

It's not the only problem with technology -- it's claimed that there has been over hundred cases of false DNA matches not caused by malice or processing errors.[0] In theory, DNA match must not be considered by courts as 100% accurate, but in fact it is.

On the other hand, there were cases when human rights advocates or journalists were claiming that innocent people were jailed but that turned out to be false, like people getting caught on camera doing the same kind of crime again after they served their sentence.

same with stenographs. We keep inventing new methods for the police to make up evidence.

I don't understand, could you elaborate on that?

I apologize, I got the terms mixed up, I meant a polygraph

Yep, I got the impression that courts consider polygraph only when the results implicate the accused. Good thing that by law they cannot force you to get questioned with polygraph attached.
