Tony,
I almost though you were spying on me being a civilian. I had the same incident have happen to me. The man that drove the truck, he struck a car while backing up. Then he re-park his truck and come out to view the damage and looked around to see if anyone had come running out to claim the car he just hit. After waiting for 3 minutes, he jumped back into his truck and took off and not knowing that I was watching him the whole time. I got a called from the owner in 30mins., within 1 hr his insurance company called me for my statement.
Back to the stolen BlackBerry, hope you catch him. Let us know what the Police had to say about your evidence.
