Security is becoming a major concern worldwide for travel and others domains, due to terrorism​ and other attacks.
However instead of improving technology. Security is focused on making it more of an inconvenience to the public.  Don’t bring this, don’t bring that. 

Focus on improving and making technological advancement across airports and public domains. x-ray machines that review parked cars. Intelligent CCTV cameras that do behaviour analysis. And much more.

It’s an IT world out there, security cannot lag behind.
