Invisibility cloak

Any Harry Potter fans out there? I had to say that. Obviously because its one of the only movies I can think of recently that has an invisibility cloak in it. In the movie it was magic, however, to Burkley's engineering team, it's a very real possibility. They managed to bend light in directions it does not naturally alter itself, to make a 3 dimensional prism vanish. Very little of the light was lost during bending, which is very important, because it results in high definition. It would look stupid if a giant ball of crinkled cellophane were floating around, because it would be obvious and really not that impressive, however, the vanished prism was no crinkled ball of cellophane. The possibilities are endless, especially when for military application. Colored camouflage is great for soldiers in the environment because they blend in. However if camouflage were distributed that resulted in vanishment of whatever it encases is a lot farther than just blending in. The technology involves nanowires that allow a form of negative refraction, Obviously the technology is complicated. What would the effect be if this was created? Guns were at one point high tech, now they can illegally be purchased on the street. Would an invisibility cloak have more pros or cons? It's a technology I would really like to see developed, especially for militant purposes but it could definitely have applications for assistance in breaking the law.
