When can you video the police?

Sixty-four percent of adults in the United States own smartphones, according to the Pew Research Center. Four years ago, about half that number did.

Many depend on their smartphones for online access, whether they’re applying for jobs, checking their bank accounts, paying bills, following breaking news events or sharing photos and videos. Never has it been this fast and easy to take a photo or video and share it online for everyone to see.
