This ruling doesn't seem to help avoid the fishing expedition. If anything it almost encourages additional fishing to justify the time it takes to allow backup units to arrive. I mean it doesn't really help outline what is reasonable it doesn't prevent the search if the dog had already been in the car. All it does is create a very slim frame up where you can't wait for another unit to arrive, because you announced you where done with the ticket.
I've been pulled over maybe 4 times since I got my license. I've never had a citation be a quick procedure Normally, just writing the ticket can take 15 minutes. I can think of a one speed trap where I was literally told to wait in-line for my ticket. So, I fail to see how this will help as its just to vague. . Someone above is mentioning forfeiture laws over used in drug corridors. Nothing in this ruling will prevent that, I just suggest you make everyone fill out receipts and better explain why you have large sums of cash on you, because this ruling isn't going to protect you.
