1. Avoid where the masses are going, those camps at the best will be cramped and if its a disease then it will spread like wildfire. People who are bitten in the beginning may make a break for these "safe" spots thanks to some sort of self-preservation instinct despite only accelerating the problem. I won't be changing up too much from my other plan I posted in the stickied thread.
2. This position is a little bit more complicated as if your prepared you lack access to your supplies. I would probably talk to the police officers and try to get a more detailed report of the situation but failing that I think I would probably make it my first priority to get out of the immediate area. If I am within the direct area of the zombie outbreak (ie I am at a mall McDonalds and the guy at the counter starts ripping the clerk's throat out) then I would probably focus on suppression. Sorry but zombie or not, you start munching on someone I am going to destroy you. That is what the mentality has to be.
