Aerosol Spray to Identify Bombing Suspects

RedHanded writes "Forensic chemists at the Hebrew University of Jerusalem have developed a color-changing spray that can identify people suspected of making or planting bombs. The chemical turns from yellow to bright red when it comes into contact with urea nitrate, an explosive residue that may be left behind on the hands of someone who has handled an improvised device."

sheesh, false positives.... Why bother when you're the gov't. Just hand your agents cans of red spray paint and arrest everyone. We're just cattle anyway. It doesn't matter if they actually catch the right bad guy, as long as the blame can be squarely placed on the shoulders of somebody already in custody.
