What happens if the National Park Service fences off scenic lookout points at the Grand Canyon’s south rim near the head of the Bright Angel trail? Would it prevent the occasional suicide jumper? Not a chance. (The National Park Service tried this in the mid 1980s). People will either gore themselves on fences and posts or they will end their lives on the road in a high speed automobile, putting others at risk. Either way, tourists will be stuck with looking at the North Rim and the Colorado River through prison bars.

Let’s move from analogy to reality. What happens if you jam cell phone signals on tunnels and bridges. Will it stop a terrorist from remotely detonating a bomb? No. But it will certainly thwart efforts to get rescue and pursuit underway. And what about personal encryption?…

Gadgets and apps are finally building encryption into their wares by default. Does a locked-down iPhone or the technology that businesses use to secure trade secrets and plan strategy among colleagues enable criminals. Not even close. But if the FBI criminalizes encryption, they cripple the entire American economy. After all, the Genie is already out of the lamp.
