A federal judge has denied bond for the four Georgia militia men accused of plotting terror attacks against government officials.

U.S. Magistrate Susan Cole said Wednesday there was too much evidence that the men took "concrete action" to carry out attacks to release them. Prosecutors argued over three days of hearings that the defendants posed a danger to the public.

Defense attorneys said the men never planned to carry out their bold talk. They said they intend to appeal.

Investigators have accused 73-year-old Frederick Thomas and 67-year-old Dan Roberts of conspiring to obtain an explosive and possessing an unregistered silencer. Authorities also charged 55-year-old Ray Adams and 68-year-old Samuel Crump with conspiring and attempting to make ricin, a biological toxin.

The four men have pleaded not guilty.
