alt Hacker NewsJudges generally do not evaluate the quality of evidence. Unless the defense challenges, it's assumed that the prosecutions claims are founded in fact. It doesn't matter if the prosecution alleges you did six impossible things before breakfast unless the defense disputes these allegations.
A judge that has no reasonable doubt with this sort of evidence has no business being a judge.
We don't know what defense did in this trial but not picking up on the username mismatch and the assumed non-challenge of the evidence is telling as well.
