Goddamn even if the cops leave the phone locked to view the ID, they’ll just pocket the phone afterwards and “give it back to you when we’re done here” – you willingly handed it over to them, they can keep it.
Now they know you can’t be recording them. You want to hand over the one thing that they know might keep them honest?
Are people just not paying attention? How the fuck can anyone be in favor of this? You want your ID on your phone so bad, get a sticky ID holder and slap it on the back.
