I've made mistakes like this one in a blog post before. Maybe even on an exam in the past couple of decades. Never in a brief, though. I don't think. Definitely not in an opinion.
"On page 11, in the third full paragraph, delete the sentence: 'Defendant Chavez was driving Alvarado’s pickup, with
Rodriguez as his passenger.' and substitute the sentence: 'Rodriguez was driving Alvarado’s pickup, with defendant
Chavez as his passenger.'"
But that's what edits are for. Nice change.
