well yeah the keychain does seem too much to me, but a desktop launcher button (i've thought of using recaller for much the same purpose before, but its easily deleted, smashed removed) is easy to press as you get pulled over in the car - front camera record would be useful if you have a gps cradle. or if you already have the headset on walking down the road when they flash the lights, even if it just uploads a video feed of the inside of your pocket along with the audio, its still useful. the police dont have guns here, but i'm pretty sure they dont just shoot on sight, if they have already pulled a gun and shouted get on the floor then yeah, forget about the phone and do what you're told.
