...if law enforcement's best chance of prosecuting someone is using files which are encrypted, then the case is likely weak to begin with--and/or they are rushing through the investigation.
If you really need to get at encrypted files, there are ways to get them, but patience is a must along with a good enuf reason--and enuf evidence--to receive a warrant to tap into an individual's cyber communications.
You have to wonder, just how tech savvy a government is, who keeps launching this fight against encryption.
Perhaps it's about time Australia's citizens to begin looking at who they are voting in to government--and placing a high value on someone who understands technology beyond typing on Twitter.
