While basically being on Apple's side here, as I understand it, jailbroken devices are unofficial builds of iOS that have some security features removed (e.g. limits on which apps can be installed).
Is it not possible for law enforcement to get what they want from that, if all they want is a custom build of iOS that can be hacked around? And why is it even possible for that to work if the data is supposed to be kept secure?
Most previous jailbreaks required an unlocked device with passcode disabled and find my iphone turned off (because passcode encrypts things).
I'm still waiting for JB for 9.2.1 or 9.3 when released but there are already semijailbreaks (browser based installs a temporary app) and some unreleased PoCs, but Cydia MobileSubstrate and other tools need to be ported / verified too.
Perhaps if Apple allowed the devices to be officially customer hackable (like flux, springboard replacements, transmission, 3G unrestrictor and changing fonts), there would be less need to develop exploits... Unfortunately, there is great demand from governments to buy exploits and keep those secret (not a conspiracy but tools in a market)
