Re: My sympathy meter is broken
The issue of a probable cause search warrant creates a legal exception to the normal expectation of privacy. An affidavit that includes the information about the computer the article describes and a statement of the fact of visiting the porno web site will get a search warrant to a near certainty.
That said, those accused of illegal trafficking in pornography, even child pornography, are entitled equally with others suspected of criminal activity to fourth amendment privacy protection until probable cause is sworn in a warrant application. and formal presumption of innocence until and unless convicted.
