I may be misquoting, but I remember Mr. Miyagi saying something like "Best block for punch, no be there," in the movie Karate Kid.

My Number One plan for riots is to not be around crowds and to get out of built-up areas as quickly as possible, if conditions appear to be degrading. If that cannot work, my main backup plan is to find the most inconspicuous and most secure place to hide, and wait it out.
