Re: take audio
I do not see why you couldn't take audio of an accident. Most modern cell phones are capable of recording audio, video or both at the same time. All you need to do is just turn on the recording function on you device and wait till an accident happens. Also, you could record phone conversations, as many subjects are required by law, and then if an accident happened, you would have an audio of the accident. There are many possible scenarios you could come up with where the phrase would be applicable.
