Just to remind folks: the OP headline is (at best) wrong.
The guy did not get sanctioned for using free speech at all.
He got sanctioned for breaking the law.
He was put in jail for exposing the police for beating an underage high school student.
Disagreement with that law is all well and good, but lets not pretend that his punishment came for something other than what it did come for.
Putting people in jail for videotaping the police is a bit more than "disagreement," it's pissing on the constitution.
When the first was written, the printing press was the technology for exposing corruption and criminal acts by the ruling authorities. Now we have video, but the principle that we can NOT prohibit freedom of the press, now video, remains paramount.
The ONLY check we have to the encroaching authoritarianism of our government is exposure, detailing and communicating what they are doing. IF you succeed and those who expose wrongdoing by the government are imprisoned, rather than the wrong doers, then any hope of liberty is lost.
