Ironically, biometrics are probably your best defense from intrusion. The government can have your password/passcode in 5 minutes just by calling Apple/Google/Verizon/AT&T/etc, but biometrics requires that they physically obtain your device in order to get into it. Furthermore, biometrics aren't used for anything that can be exploited presently. A thief can't just email your bank a copy of your thumbprint and clear out your account...no institution would ever accept anything other than you being physically present to enter your print. I often wonder if the people warning us about the perils of the fingerprint scanner actually believe what they say, or merely want the rest of us to believe it. Fact of the matter is, even if the government could figure out a way to "use" your prints it would mean that they wouldn't even need to bother as they would probably already have all the info about you that they wanted.

LOL. Good point. Hell, if the government really wants your fingerprint and if you've ever touched a doorknob...guess what?
