  • Do the police take your dash cam if they pull you over? Does that show on their own badge cam?

    Streaming live video takes a lot of bandwidth and connectivity from a car can be intermittent, but maybe it’s enough to send a timestamped hash every few seconds, so there is tamper evidence in case of a deletion.

    Anyway, deleting video through a dashcam user interface is like deleting a file on a computer: basically a little bit of metadata is overwritten but the underlying data can usually be mostly recovered with filesystem repair or forensic tools. To really delete it for sure you have to either destroy the media or use special tools to overwrite the data blocks. Or just running the camera for a long time (to make sure the freed blocks get re-used) might do it.

    You could also stream to another phone or computer tucked away elsewhere in the car, unless you expect the whole car to be seized.

    Thanks yeah I don’t have a kobo reader so was asking if there was a way to read paid-for kobo downloaded books that have drm, similar to how decss lets you watch DVDs that you bought. I don’t mind paying for books but don’t want a locked down reading device with it’s own crappy software and possible invasive phoning home.
