Apple, Security, privacy,FBI, hackers a master key?

The FBI is asking Apple to create a master key tool that would circumvent a feature that deletes all of the information on the phone after 10 failed password attempts. [link to www.wired.com]
I think it will make all iphones a easy threat for hackers to use the back door also and then no ones information would be safe. The whole identity threat would hit the fan and if you thought you were safe you won't after the master key for the back door would be put in.
I think the FBI should go about hacking the phones with better hackers than try to force a easy fix for something they can use for any reason.
OUCH!! that would hurt
