Judge: Cops Can Impersonate Owner Of Seized Cell Phones
Aryden writes with news of a recent court decision in which a judge ruled it was acceptable for police to impersonate the owner of a cell phone they had seized, in order to extract information from the owner's friends. The ruling stems from an incident in 2009 when police officers seized the iPhone of a suspected drug dealer, then used text messages to set up a meeting with another person seeking drugs.
"'There is no long history and tradition of strict legislative protection of a text message sent to, displayed, and received from its intended destination, another person's iPhone,' Penoyar wrote in his decision. He pointed to a 1990 case in which the police seized a suspected drug dealer's pager as an example. The officers observed which phone numbers appeared on the pager, called those numbers back, and arranged fake drug purchases with the people on the other end of the line. A federal appeals court held that the pager owner's Fourth Amendment rights against unreasonable search and seizure were not violated because the pager is 'nothing more than a contemporary receptacle for telephone numbers,' akin to an address book. The court also held that someone who sends his phone number to a pager has no reasonable expectation of privacy because he can't be sure that the pager will be in the hands of its owner. Judge Penoyar said that the same reasoning applies to text messages sent to an iPhone. While text messages may be legally protected in transit, he argued that they lose privacy protections once they have been delivered to a target device in the hands of the police."
The fact the person is a suspect is irrelevant. The police legally seized the item.
Your hypothetical is illogical in the extreme, unless you are assuming the issue includes the authority to create a body double as well.
As for your assertion that such action requires a conviction first, I've pondered a bit and come to the conclusion it's so flawed as to not even warrant a cursory response. Maybe someone else here will take you up on it, but it's not worth my time.
