If at first you don't succeed, don't try again?
A pair of brothers, Daniel and David LaDeau, allegedly exchanged coded messages while David was in jail. The messages contained information on how to obtain and conceal child pornography. Police obtained a warrant and searched Daniel's home, where they found USB flash drives containing child pornography.
Daniel was charged with one count of possessing child pornography (18 U.S.C. § 2252A(a)(5)(A)), an offense which carried up to 10 years in prison. It should have been a slam-dunk case, but the actions of investigators, who threatened to reveal the allegations to Daniel's ill wife, moments before she was headed into life-threatening surgery, led the district court to suppress the evidence.
