Wiretaps in the US
• Real-time interception of communications content.
• Includes– Voice communications– Text messages / IM– Network traffic (think: tcpdump)
• To get one, law enforcement must get a “super warrant”: probable cause +

If you are going to break the law, and don’t want to be wiretapped, stick with something safer…

Phone surveillance increases each year, while other forms all decline
(due to more intercepts by states,not the federal government)

Network Wiretaps?
• Law enforcement agencies are simply not performing real-time data network intercepts of communications content.
• These stats do not cover FISA / intel agencies, who almost certainly are.
• Law enforcement are instead relying on access to stored communications (cheaper, easier, etc).
• Why tap your ISP in real-time when your email provider will readily give up the files later?
