Because of this, anyone who wants to know knows when you’re home or at work and when you are not. Anyone with access to the internet can not only look up any physical address, say of your home or workplace, but can get a fairly recent photo of it using Google Earth and virtually walk around it using Google Maps with Street View. 

Want to know the value of home, the average income of a particular neighborhood, or a person’s credit score? There’s a website for that, too. 

Criminals are catching on and taking full advantage of this readily available information and technology to target individuals and businesses to plan their crimes and their escape routes. In Britain, for example, thieves are using Google Earth to target churches with lead roofs and then sell the stolen goods on the lucrative metals market. 

Entire governments are even getting in on the action to spy on and attack other neighboring countries in similar ways. 

Thanks to Wikileaks, no email, no matter how confidential, is safe. Your cellphone? Forget about it. Police in Florida recently used the GPS locator built into a stolen cellphone to find three teenagers accused of a home invasion robbery. Our guess is that they could locate your cellphone, too. 

In short, everyone knows what you’re up to because you’re telling everyone what you’re up to. 

Don’t even think about sharing your thoughts on committing a crime or the authorities might hold it against you. A staff member at T-post even cited a personal example whereby a friend was allegedly refused entrance into the U.S. after security agents said, to their surprise, “You wrote on Facebook that your were coming to the U.S. to work illegally. And we can't have that."
