'How to kill with a knife' seach on the internet used in court

Over a period of time, researches who deal with privacy issues have proven that it is possible to identify a person just from being able to look at their search records. If this required proof, then one need no look further than this case. In a case in the United States where a father was accused of killing his wife and daughter with a knife, it was revealed that he searched for the words 'How to kill with a knife' on Google.com six days before he actually carried out the murder:

A Briton accused of murdering his wife and baby daughter made an Internet search on 'how to kill with a knife' just six days before their bodies were found, a US court heard. "A search was made on Google.com. Search was made with six words. 'How to kill with a knife,'" Lawrence James, a forensic computer expert and 20-year police officer, testified in Neil Entwistle's double-murder trial.
James told the court that the Google search was made January 16, 2006, six days before Rachel and Lillian Entwistle were found shot dead at their home in an upscale Boston suburb on January 22, 2006. On the eighth day of Entwistle's trial, Assistant District Attorney Daniel Bennett told the court that records showed the suspect had searched the Internet for female escorts only hours before the murders.

It is now wrong to think that searches on the internet are anonymous. ISP records, home computer records, all such evidence can be found and inspected based on court orders and used to build a stronger case.

Couple puts 7 day old baby girl for sale on the internet

This is the second time this year that such a thing has been reported. The internet, especially classified sales lists such as Craiglist have been used by people to sell all sorts of things, essentially as a online flea market. But no one can expect such lists to be used to sell human babies; in this case, a couple battling drug problems put in a young baby girl for sale on the internet. They were only caught when another woman saw the listing and reported it to authorities:

A couple put their seven-day-old baby girl up for sale for USD 10,000 over the Internet, Canadian police has said. The baby was seized by social workers in an apartment in this Pacific coast city while the parents, who have a history of drug problems, are under investigation for human trafficking, said police Constable Tim Fanning, just days after a similar incident in Germany.
The ad read "Must have!!!!!!" and offered a baby girl for 10,000 dollars. It described the child as seven days old, "very healthy and very cute. Can't afford and unexpected, looking for a good home, please call ASAP."

For no fault of hers, this baby has parents who are looking to sell their baby. Even considering that this is a hoax and a prank, it is very difficult to convince people that parents of a 7 day old baby could go so far as to think about putting their baby for sale on the internet (this is certainly not humour).
