A madman in France? How come he's always at crime scenes!

Wu Liang, a psychology master's graduate who passed the bar exam on his first try, transmigrated to a parallel world where courts seemed to uphold legal principles above all else. So, if one could dissect legal provisions beautifully enough, wouldn't one be invincible? Running over a sleeping old lady in a garage? No duty to investigate, innocent! Stabbing her twelve times in self-defense? Justifiable self-defense, innocent! Death of a lover after a passionate encounter? Accident, innocent! ...Wu Liang thrived thanks to his mastery of legal anatomy, possessing a bit of a detective's charisma. Until one day, he was cornered at the door by the head of the criminal investigation team. The team leader, eyes bloodshot and teeth clenched, demanded, "Wu Liang! Why are you always involved in murder cases?" Wu Liang feigned innocence: "Officer, please watch your language. According to Article 246 of the Criminal Law, you are suspected of defamation." "Then how do you explain that all your clients were released in court?!" Wu Liang asked in surprise: "Isn't it because...they are truly innocent?"
