There are many different industries where accuracy is extremely important. Mechanical engineering, for example, often requires that significant digits be rounded to the nearest thousandth decimal point, especially in aviation and aerospace industries. If their measurements are off by even the smallest fraction of an inch, the entire structure or machine could fail, and with the case of space-going vehicles, billions of dollars can be wasted. Seattle court reporters follow the same principle of precision in their work, but with different consequences.
Although it is unlikely that the results of most civil lawsuits will end up costing millions or even billions of dollars, the outcome is extremely important for those people involved in the case, and those who go after. Court proceedings are not just recorded for the benefit of the attending judge and legal teams, they are recorded for future court cases as well. In order to quickly try similar future cases, lawyers are able to search the records of past lawsuits.
This makes the justice system a little more efficient and allows past cases to be revisited with astounding accuracy as to everything that was discussed. Seattle court reporting firms train for several years to be completely proficient and be able to accurately record all statements made by the judge, lawyers, witnesses, and jury. Modern attorneys are able to look back several hundred years in term of court records and likely so will the lawyers of the future be able to do so.
