Of all cases to lament the lack of evidence for, why this one? We have video from multiple angles covering the entire event, dozens of witnesses, forensic evidence. Lack of evidence isn't the reason this case is polarizing.
Pretty much the week of we had 3 different angles of every altercation.
Also, Rittenhouse's lawyer released a breakdown of the different angles more than a year ago.

All of this was suppressed until now for emotional outrage.
