The choke points are definitely an issue at airports but also at sporting events, where masses of hundreds of people are crowded around a gate getting in to the stadium. I think they need to setup a maze system where passengers/fans queue in to a system where can be scanned as they go through and directed to lower and higher risk areas something bullet/blast resistant where people can be physically isolated from each other (and from gaining access) as they pass through security and everyone can be locked down (or automatically directed to exit the facility) if an event happens so there isn't a free run through security. And make it large enough where people can get in to the system quickly so you don't have large groups of people standing waiting outside. Something with lots of angled areas as you enter and get you isolated, scanned directed in to the facility or over to higher security area for further processing.
