I don't think there is one "right" thing to do, no one size fits all solution...and that applies to both rural and urban settings. It all depends on an individuals circumstances. You could have 2 seperate people in exactly the same situation who come up with completely opposite solutions, both of which being right for the individuals concerned and their differing circumstances.
I'm bugging in until it gets too dangerous...or appears to be at least. Other people's first choice might be to head for the hills at the first sign of trouble, like I said earlier, what works for some wont work for others.
If you are living in an urban environment though, one of the lessons from the riots is to be aware how quickly things can kick off and spread out of control, more population = larger amount of people ready to loot/rob at the drop of a hat, so the means to (legally) defend my family and property would be high on my agenda.
That reminds me, I must get down the Archery range for some more practice...purely for the sport you understand, I would't dream of pointing anything sharp at a looter
