Cellphone Privacy In Canada: Encryption Triggers Need For Warrant
codegen writes "The Ontario Court of Appeal has just ruled that the police can search your cellphone if you are arrested without a warrant if it is not password protected. But the ruling also stated that if it is password protected, then the police need a warrant. Previous to this case there was no decision on if the police could search your phone without a warrant in Canada."
This seems directly equivalent to "If your front door is unlocked the police can come in and snoop around without a warrant"
You could say the same thing with several other things like...
"if your car is unlocked they can rummage through it legally without a warrant"
and
"If your fly is down, they can do a cavity search legally without a warrant"
Makes sense to me. If I were to be arrested without a warrant, the police can go through all the pockets of my wallet and look at every card and piece of paper I have in there, however if I were to have a lock on my wallet, they would need a warrant to open it. The modern cell phone is very much the same as the wallet and datebook of the past. If it's not locked, they can go through it.
A real world analogy: encryption is like a room within a room.
If you were to enter a residence, and find it divided into apartments, you'd probably have to get a warrant for each locked, separately numbered door.
The real question is whether one individual can have multiple rooms within a room. If your phone and computer are encrypted, do they need a warrant for each?
The ninth circuit is not the supreme court. In fact, the supreme court overturned the ninth circuit's ruling: http://arstechnica.com/tech-policy/2012/01/supreme-court-holds-warrantless-gps-tracking-unconstitutional/
