i don't think that the defence is allowed to break rules in court. Like, once the trial starts, like, the bad guys are still lying and they're tricking  and they're being tactical. And if the prosecution wasn't allowed to be tactical, sin the prosecution should lie. This is an interesting point that i think comes up when i argue with people the judicial system sometimes. It's not like we all hold up our hands and say, ok, there's no more good guys and bad guys. Let's just walk in a room and everyone tell the truth, and then justice will be done.
