Channel 4 drama - Blackout

[Bjm]

hi,
the thing it made me think about was that as part of our preps we are ready to defend ourselves in various ways, bows,knives, maybe even guns, now at what stage would you have used them if you were the prepper?
i know we are not as stupid as the one in the show but even so.
and at the end of the program when the lights came on what would you do withe the bodies and how would you cover your tracks?
