So far we've had shooting's at grocery store, craft store, several gas stations, and a school. If it is terrorism, I'd be careful around Churches and Theaters.
I think it might be time for some
very brave and vigilant people to organize (or do it on their own) some type of neighborhood watch system where people station themselves in their cars in shopping center/mall/gas station/school/theater parking lots and keep their eyes peeled for "suspicious" vehicles and people. A pair of binoculars might help. Of course, on the other hand, people might think
you're the suspicious one and call the cops on you, LOL! Still, it's an idea worth looking into.
These people were shot while doing their everyday business. Nobody was paying attention to their surroundings--which you shouldn't have to watch out for snipers while walking out to your car anyway. But now we know what's going on. A "neighborhood" watch would be a good idea, I think.
