I haven't actually found the section of the California Vehicle Code that prohibits taking photos with a cell phone while driving (CVC 23123 thru 23125 prohibits talking on a phone (without a hands-free device or while driving an emergency vehicle) or texting on a phone).
Now I admit, I have occasionally answered the phone while driving. I have played mp3's while driving. I have used google-maps/GPS while driving.
I have not played Angry Birds while driving. Yet.
But when it comes time to execute a driving-by-shooting, I don't use my fancy phone camera.
I use a real camera.
Digital rangefinder, bam!
Digital rangefinder, bam!
Digital point-n-shoot, bam!
Cross-processed slide film, bam!
