No....let me explain
it is illegal for you to drive faster than the posted speed limit
some people drive faster than the posted speed limit
You may have a good excuse to be driving faster than the posted speed limit, and if you can justify your reason in court, then you will be absolved. You may have had a medical emergency. This does not, however, mean that anyone with a medical emergency is allowed to speed. There is no law that specifically states that you may speed, the courts do allow exceptions though. If the law stated that an emergency situation allows you to violate all traffic laws, and you are allowed to decide what constitutes an emergency, then many people would be driving recklessly on the roads.
The point is...there is a clear difference between making exceptions, and flat out allowing something. Previously we made exceptions, the Patriot Act flat out allows the violation of civil liberties.
