I’m sure there’s some reason why Joshua Marpet’s invention won’t work. Or if it does work, why hidebound police departments won’t adopt it. Whether or not the Flarecam finds commercial success, you’ve got to admit that the concept of putting a miniaturized TV camera into a flare gun round for eight seconds of live video is, dare I say it, neat. “The weapon could be used by police to get an idea what the bad guys are doing,” slashgear.com reports. “The flare gun uses the Firefly single-use spy cam developed by military contractors from Israel. The device has potential use in the civilian sector as well.” By that they mean cops, right? Otherwise, what?
