Urban Survival Guide by David Morris is one of many survival books out there, though it separates itself by being more of a 'bug in' book (survive in place) versus heading out into nowhere land and surviving off nature. Something I point out in a previous post that sometimes it won't matter where you go trouble will be there. The book isn't tremendously detailed, but it brings up many issues one faces in an urban suburban setting. What I really like is that the book wasn't just published and left out there. The author has continued the process of learning and preparing and puts out a newsletter as well as offers classes, equipment suggestions etc..
In light of the recent riots in London as well as continued economic destabilization in the EU and US, the advice and information seem rather timely.
If wide spread riots occur will you be able to get from work to home? Can you survive in place away from your supplies. Can you repel those that wish to take or simply burn the place down? These are tough and even scary questions, but unfortunately reality seems to have taken on a reality of it's own.
