I think it&#x27;s a good idea to leverage technology . . . that just might not be the right idea . . .<p>How about an app you can choose to run if you&#x27;re in a terrorist&#x2F;robbery&#x2F;hostage situation. That will allow the authorities to use your mic and cameras to get a picture of what is going on.<p>How about using interconnected sensors (around towns&#x2F;large crowd areas) to detect when a vehicle&#x27;s weight is abnormally large (car&#x2F;truck bomb). Then alert authorities to the vehicle.<p>A type of bomb proof enclosed area you have to walk though to enter a stadium that sniffs for explosives and uses imaging to determine if you are a threat, you could be detained inside if wearing an explosive vest for example or have a gun. This would prevent bombers from being in a crowd when detected.<p>Keep thinking outside the box.
