Also, was it the guy that filmed it, or the other guy who shared it?The charges were for having and sharing, not filming.
In the United States, as of 2009 ten states had laws on the books requiring that people at least notify law enforcement of and/or seek aid for strangers in peril under certain conditions: California, Florida, Hawaii, Massachusetts, Minnesota, Ohio,Rhode Island, Vermont, Washington, and Wisconsin.
Don't know if the filming expert was required by law to do so. The most important thing to remember here is Mo was not affiliated in any way with the alleged rape, the filming, and the original distribution of said VID. The real question is can he be charged with both laws in California?
