I didn't read the whole article, but did they send letters to the software developers too? Seems to me, Apple approved an otherwise legal app, albeit one in a gray area, but legal.
Distracted/impaired drivers are dangerous to us all on the public byways.
A gray area? I think you may be going a bit color blind there. Surprise DUI checkpoints are totally illegal under the 4th amendment. No question about it, no gray area. They are illegal. Period. So to get around that, the government removes the "surprise" part, and announces them all in advance.
The dates, times, and locations are all published before hand in the newspaper, and on the radio. The thinking behind that is if the people know about them in advance, then they are "consenting" to the search if they choose to drive that road. Announcing the location of the checkpoints, in advance, is the
ONLY thing that keeps them legal! This issue has nothing to do with "censorship" since it is the government themselves who are publishing the locations, as they are legally required to do.
This app is no different from the Weather app or the Craigslist app in that it brings information that is already published and publicly available - to your phone. Once again, notifying the people of the dates, times, and locations of these checkpoints is required by law! The government must provide this information or they cannot set up a checkpoint.
I'm against drunk driving, don't get me wrong, but I'm also against drunk lawmaking, which these four Senators are clearly guilty of.
