The case involves the FBI arresting a child pornography suspect

A U.S. court has ruled that the FBI can hack into a computer without a warrant -- a move which is troubling privacy advocates.

The FBI, however, managed to take over the site in 2014, and then tracked down and arrested its members by hacking their computers.

One of the arrested suspects has argued that the evidence against him had been unlawfully seized.

The judge, Henry Morgan, ruled that even though the FBI obtained a warrant to hack into the suspect s computer, none was needed.

For example, hacking is much more prevalent now than it was even nine years ago, he said.

Rumold, however, expects that this part of judge s ruling probably won t hold up in appeal.
