Quite a few people here have very strong opinions based on only knowing the news and never do any real thinking or in-depth studying, relying on the authorities to know better.
Here is a realistic scenario for you to ponder.
You are on a busy street corner in a leisure district with your wife an child. There are restarurants and caffes all around you. You enter into a medium sized one and take a seat at the table.
Suddenly there is an explosion at a table across the room from you. When you regain your senses you see that about half a dozen people are lying down around the place where the explosion occured, apparently dead or badly hurt, with some competently-looking people tending to them. The windows are blown out, the place is a mess. The rest of the patrons are shaken and bleeding from supreficial cuts but not hurt otherwise and starting to pout out into the street, as well as people from other restaurants. There is commotion, some smoke, car alarms blaring on the street. Your family is shaken but unhurt. You grab your child. Their safety is your utmost concern. You have a cellphone or whatever else you usually carry with you.
Describe step by step in detail your actions for the next ten minutes or while you are within 300 yards from the spot. Helping wounded is out of the question. Everyhing else goes.
Try not to think longer than you would have in real situation like that.
Do not expain your actions, rather allow people to post their answers and please post explanations for your actions after 12 noon E.S.T., Thursday October 16
