Ever think about what could be stored in the ports in your own country, or how old that nuclear power plant is close to the city, or what gets transported on those long freight trains with hundred tanker cars... Regulations are one thing, human error and letting things sit is another.
Port of Houston, TX is a ticking time bomb. Got enough chemicals there to start WW3 and they aren't stored too safely. Just wait till category 5 hurricane hits Houston and see them wondering what went wrong.
