freedom of speech

I am looking for the sources for two highly quoted but (as far as I can tell) never cited quotations. I prefer to have the original source - that could be journal article, newspaper article, interview, authored work, etc. but I can accept a reference to a reputable quotations dictionary or other reference work. I need page number in addition to the title, publisher, etc.

The first quote is:

You don't have to burn books to destroy a culture. Just get people to stop reading them.
~Ray Bradbury

The second quote is:
If large numbers of people believe in freedom of speech, there will be freedom of speech even if the law forbids it. But if public opinion is sluggish, inconvenient minorities will be persecuted, even if laws exist to protect them.

~George Orwell

Our local public school will be enforcing a mandatory "Campus Wear" uniform policy this year, for grades 7-12. The restrictions include socks and undershits (solid color socks and white t-shirt, no muscle undershirts). No embellishments are permitted. The size, color, length, style (no patch pockets, must have belt loops) and even the type of fabric are dictated for the pants. If a student fails to obide by the new restrictions, they will be sent home to change into the full uniform (including a mandatory black or brown belt of not excessive length, and receive an unexcused absence (F for the day). Since when can a public school deny a minor their education based on what they wear? How is it the school's authority to dress our young adults? What about skirts? How can the idea of "professional appearance" equal polo shirts and khaki pants? This sounds like Walmart clothes, not Lawyers attire. Is it constitutionally legal for a public school to restrict the clothing of a student (right down to their underwear) and do they have the authority to deny them an education based on their compliance?
