This post (the first in what is going to amount to The Fifth Element Police Week. What is this, sweeps?) is going to veer to the edge of interaction design, getting into the Venn overlap of industrial design and wearable tech.

The police seen throughout New York each wear uniforms that feature a large, circular, glowing light over the right side of their chest.

There are only two things to say that’s positive about this police light. One: Yes, it looks cool. Two: It certainly gives narby citizens a clear, attention-getting signal that something is up. This might be OK for community relations officers, who are only ever interfacing with the public. But when it comes to dealing with actual criminals, it’s a terrible idea.

It’s a terrible idea because of its placement

Imagine this scene from the chief’s perspective. When he addresses Leeloo down the pipe as she’s standing on the ledge of the building, he is in an isosceles stance, with his shoulders perpendicular to the target and his weapon held in front of his heart. This common stance would place the weapon directly in the glow of the circle. This means that his forearms and weapon will have the brightest illumination in his field of vision and be distracting. This might be manageable by coating his uniform and the back of the weapon with a super black coating to absorb much of this light. But, depending on the distance of the target, it is also likely to place the perp in shadow, making them harder to see and harder to hit.

Looking at the officer on the right, we see he is taking a different stance. He is “bladed” to the target, closer to a Weaver stance, with his body turned a bit sideways. This stance turns the light to the adjacent wall, which minimizes the backscatter and perp-shadow effects, but also aims the light toward his fellow officer, possibly distracting him or her. That’s a pretty crappy design. But wait, it gets worse.

It’s a terrible idea because it’s a giant, glowing target

What’s worse is to imagine the scene from the perspective of the perp, say, the Mondosahwans in the airport. They want to specifically shoot the police in the crowd and all they have to do is shoot towards the glowing discs. That’s right, the police in 2263 are actually wearing attention-drawing targets. Admittedly, if you are going to get shot in the line of duty, you’d rather draw fire away from the head to a place with a solid slab of bone and lots of body armor. But why draw their fire in the first place?

As we saw in another post, Zorg believes in the fallacy/parable of the broken window, and so favors a bit of destruction that encourages market activity. We also know from the film that he has a lot of control over the NYPD. It might be that he’s deliberately sabotaging the police through this design to encourage the sale of more body armor and weapons, but are we to believe that the cops themselves are willing to go along with this? C’mon. They’re smarter than this.

Improve it with a little bit of smarts

Outfit the light with a little agentive smarts, and most of these problems could be fixed. The light could simply dim when it’s counterproductive to have it illuminated. Proximity sensors can sense when the officer’s arm is in the way. Context aware sensors can sense when it might blind another officer. It would take a lot of smarts to know when the officer is being targeted by a weapon, but certainly simple audio sensors should shut it off in the sound of gunfire.
