Why was tweed so confident that nonjury would ever convict him?

Tweed was confident that a nonjury trial would favor him because he believed that a jury composed of his peers, particularly in a politically corrupt environment like New York City at the time, would be sympathetic to his position and possibly influenced by his connections. Additionally, he may have underestimated the evidence against him, thinking that his political power and wealth could sway public opinion and ensure his acquittal. This overconfidence in his ability to manipulate the system contributed to his belief that a jury would not convict him.
