PRISM (surveillance program)

A Prism is a tool used by the government to help them keep people safe. It's like a big magnifying glass that the government can use to look at the emails, pictures, and other activity that people do on the Internet or their cell phones. The government uses the Prism to look for bad people who might be trying to do dangerous things, like planning a terrorist attack or trying to hurt someone. It also helps them find out if people are breaking any laws.
