So what if you can't get an iPhone video admitted as evidence? Looks like it would be just as good to post it to YouTube.
A California man was ejected and arrested from a Santa Cruz City Council meeting after doing a silent Nazi salute. Robert Norse then sued city officials, alleging that they violated his First Amendment rights. The district court granted judgment against him, but the 9th Circuit reversed that decision 11-0.
One of the judges pointed out that anyone could see the iPhone video of the salute on YouTube.
