OneWay

Creation
The OneWay device was created out of a modified riot wall projector, used by Seattle in 2092 after deadly riots in wake over the banning of diet cola. The riot wall projector was used to deflect incoming projectiles like Molotovs and rocks, allowing projectiles to be stopped by a transparent solid wall. It uses technology similar to what you would see on ship shields in the later 2100s. That being said the projector didn't always form a stable wall and walls created could always be disrupted if the device was broken or enough force was applied to break it.

Applications and purpose
The Oneway was modified in a few ways.
 * To provide one way mirror effects to the shield allowing police to see the outside but blocking outsider's view.
 * To work out the kinks in the hand held version and provide a stronger sturdier shield, one that would survive heavy rain.
 * Upgrading existing parts and redesigning the handheld to a stationary box that can be mounted, moved and stored easily and anywhere.
 * To protect the crime scene from being washed away during heavy rain.

Some things to note is the box is not within the shield, it's mounted and projects a shield wherever it's designated to. Via the computer attached to the box (the screen can be closed incase of rain) the computer will help designate the location. Using city maps and specific measurements taken by patrolmen to create a tight strong projection to protect crime scenes. The OneWay was incorporated to the Toyko Metropolitan Police Department in 2100.
