About SD cards: That Baltimore Uprising was for me right on the
line between wiping with random numbers and physical destruction
of the card. Had I seen any police aggression aimed at recovering
anyone's camera, or heard the slightest whiff about warrants that
card would have been destroyed as soon as the files were encrypted.
Same if I had accidently filmed a felony of any kind.
The random number wipe was to destroy MOST of the content in case
some prosecutor got smart and managed to deal out a no-warning surprise.
The main danger is being captured with the card in a mass arrest, in
these cases smashing the card in your teeth is the best defense. In
fact, this is why I only use cameras that shoot onto cards that can
be easily destroyed.
I've tested wiping the cards and running file recovery, Foremost , photorec,
and other software file recovery won't get anything. Haredware recovery
from bare flash chips off an SD card is much more expensive.
About package downloads: When I used public access computers for
Internet access and only had offline Linux machines, browsers are exactly
how I used to get packages, then copy to a flash drive or even burn to a
CD in those days. This works, but resolving dependencies is a mess.
More than once this required more than one trip to the library before
everything worked. In this situation, being able to download an ISO
once with everything needed on it is a real time and trouble saver,
especially for a newcomer. Sometime soon I will download the 15.10
iso on the road so I can test the default kdenlive install with my
camera's AVCHD clips and see what happens.
I still routinely use browsers to pull packages cross-distro, from different
versions, or when I do not have the bandwidth to update APT's lists.
