The constitutional right to privacy protects us against government overreach and oppression. This right is more important than ever.Our daily lives are now stored in tweets, texts and Facebook posts. We need innovative and comprehensive laws to protect the right to privacy.Today, the ACLU testified in Jefferson City in support of such a bill. Senate Bill 84, sponsored by Sen. Will Kraus (R-Lee’s Summit).The bill regulates the use of Stingrays, also known as "cell site simulators" or "IMSI catchers." These invasive cell phone surveillance devices mimic cell phone towers and send out signals to trick cell phones in the area into transmitting their locations and identifying information. When used to track a suspect's cell phone, they also gather information about the phones of those who happen to be nearby.Stingrays can help solve crimes, but they also pose serious risks to our right to privacy.The government has an obligation to make sure the state doesn't spy on its citizens. Senate Bill 84 protects Missourians from unlawful, unreasonable, and overly broad cellular metadata searches.
