I have some questions about search warrants such as what are some issues you can see with search and seizure for technological devices? In many cases, they take the entire device with them, not just hashed copies of the data. if there is no data relevant to the crime, do you think the person who owns the devices should be compensated for having their device taken for a measurable period of time? Are there any specific reasons that a judge would approve a search warrant? What type of proof could an officer use to persuade a judge?
