Camera on the boob, allowable as evidence?

Hello to moinmoin from the sneezing Hamburg! Following a advice from the collector some time ago, I bought a camera from an internet provider “to travel along”. So there are films of high-speed rides with the Elli on… These cameras are advertised like all others with the fact that they are valuable as a “digital passenger” and in the litigation a good, incorruptible witness… What does it look like with that now? Has someone already had corresponding experiences or Is it an empty sales floss and no judge of Germany likes to gugg exciting private movies from traffic?
