Dozens of US law enforcement agencies, including the FBI, have used radar devices that allow them to “see” through walls of buildings to monitor human activity, a new report states. This has led to questions regarding how legal these tactics are.
The policing agencies began using the radar device more than two years ago without public disclosure and little notice from courts until a recent case in Colorado revealed its use to catch a parole violator, according to USA Today. The device’s clandestine use has raised questions about Fourth Amendment protections against unwarranted police searches.
“The idea that the government can send signals through the wall of your house to figure out what’s inside is problematic,” said Christopher Soghoian of the American Civil Liberties Union. “Technologies that allow the police to look inside of a home are among the intrusive tools that police have.”
