In an effort to increase public safety, the FBI has created a service that sends e-mail alerts which will let recipients know that there is new information on its web site.
After you sign up, you will get breaking news and alerts sent to your computer or wireless device. According to their web site, the alerts will contain information in several different categories such as terrorist threats, missing children, fugitives, the latest scams, and more.
The FBI started offering this service in October. Since that time, they have sent out more than 600,000 alerts to almost 14,000 subscribers.
Their web site gets between 2 and 3 million visits a month (they should put up some Adsense ;:) and has several tools visitors can use. For example, you can report a crime right on the site, assist in finding fugitives and missing persons, apply for a job, request FBI records, get personal safety tips as well.
Check it out, they already know who you are ;).
