The Internet is changing everything: providing voice to the voiceless, undercutting power - yet also creating new means of control as forces push back against authority. In this episode meet an abuse victim and activist who uses technology to document and report police abuse; the heir to a rabbinic dynasty who's turned away from Brooklyn's Hasidim after finding a world he never knew existed online; and an entrepreneur whose 3-D printing technology enables building untraceable, undetectable guns from the comfort of your own home.
