There are more than 300,000 smart phone apps. But, on Wednesday a leading phone-maker pulled its programs that list DUI checkpoints and other speed traps after lawmakers complained.
Responding to a letter of complaint from four U.S. senators, the makers of Blackberry pulled two applications that warn users when they're approaching a police checkpoint.
The GPS-based tools let users report the locations of DUI checkpoints, speed traps and red-light cameras.
Critics believe it's an attempt to regulate apps and that it violates freedom of speech.
“So more people have notice, isn't that great?" said Ellis who calls himself "Mr. DUI.
"That's what the law says. It says you have the right to have notice. So now you can do it with electronics? Wonderful,” he said.
