I think everyone should have a problem with the govt hacking into private property.
If you commit a crime, you lose your privacy.
If you get pulled over and the cop sees what looks like heroin and a syringe, he has the right to search that car, he has the right to confiscate evidence from that car, he has the right to tow that car, he has the right to take all personal belongings in your pocket, wallet or purse and go through that as well.
If a terrorist kills several people, yes, the authorities have a right to search that cell phone if they can.
