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.
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/
