Here's mine for the low end: a study examining attorney perspectives on plea bargaining https://pmc.ncbi.nlm.nih.gov/articles/PMC6368263/ and multiple sources citing 2-8% of felony guilty pleas involve innocent https://testif-i.com/issues/plea-bargains/ https://www.themarshallproject.org/2014/12/26/plea-bargainin...
At 2%, that's 98% guilty - which is what I meant by "vast majority." If you're claiming 25%, prove it.
