It appears to me that the defendant's lawyers are arguing that:
- Not all lies should be treated the same under the law. Defendants shouldn't be held responsible for lies that aren't material to a naturalization decision.
- Trivial lies shouldn't be punished if they are on an application for citizenship, for instance.
- Lies made during naturalization proceedings are different and should be punished even if a lie is insignificant.
- The jury - not the judge - should decide whether a lie is material to the case or not.
