Sulla, on the other hand, decided it was only important to be very, very clear on the precise acts that he was legislating against, and so he explicitly outlawed killing people on purpose with arson, by giving false evidence or arranging for people to give false evidence in court, by presiding over a criminal trial with the intent of executing someone, by taking bribes so that someone will be found guilty, or – weirdly – by poison, and ruled that it was no longer legal to carry a knife or weapon in Rome with the intent of killing someone.
