Watch What You Google
Apprently, this woman in New Jersey killed her husband and the most damning evidence was that she googled phrases such as, "How to Commit Murder," and "undetectable poisons." They're calling it a Google fingerprint and we certainly all leave one. Every website we search can be categorically discovered by anyone with the means and the knowhow (and presumabely, the legal authority). This certainly raises a lot of bigger questions, but we'll save those for another day.
Let that be a lesson to all of you who are going to ask.com and typing "kill+boss+scott+free."
