He's taking a fall for his demented father, thinking this will distract attention from the laptop's evidence of "the big guy" laundering money or taking bribes or whatever. His conviction is also a way for the DP to compare this to Trump's being found guilty of nothing substantial and claim, "See? Nobody is above the rule of law."

Hearing that idiotic expression "rule of law" any time a political enemy is railroaded into court or jail is enough to make me vomit.
