special relativity

Most textbooks and teachers (at least all that I have seen or known) introduce special relativity by introducing two postulates:

1) The laws of physics are the same in all reference frames

2) The speed of light is independent of the speed of the source and the observer.

I have always thought that these are redundant. Isn't 2) implied in 1)?
