Actually, our laws are written by elected officials - state representatives and the U.S. House of Representatives, many of whom don't have a background in law or any legal education. Apparently, you don't even need a high school diploma to run for office and get elected, though we've discovered recently that a GED is strongly encouraged.
Lawyers just argue the law, which is too often ambiguous, since we have so many reps without an education in law, or even basic critical thinking skills. It's up to judges and juries (with many jurors also lacking in an education in law), to interpret the law. And it's up to judges to apply the law. I guess that's why our legal system is such a mess and companies like the 13 feel comfortable taking advantage of the system.
