In 1972, Bill and Miriam Brownell started a non-profit anonymous hotline to stop drug dealers. Now, their organization services cities, schools, and Native American reservations. The purpose of the service is to relay tips about criminal activity to law enforcement agencies while keeping the identity of the tipster completely anonymous. To report crimes, tipsters can fill in the form on the web page or call the telephone numbers listed there; these are continuously staffed by live operators. Information leading to arrest and conviction may win the tipster a reward of up to $1000.
