I think that old saying a few rotten apples spoil the whole barrel def. applies to this thread.
just because a few lfs owners do keep illegal fish doesn't mean they will be able to keep doing it.
i live in Northern CA, and i knew a lfs owner, really nice guy and what not, and he kept an asian aro in the store by his cash register for a long time, and at the time, I didn't even know it was an asian aro until one day, i came to the store, and the fish was gone.
I asked what happened, and apparently either someone told the FWS dept or they were doing random checks, and fined him big time. His only break was they didn't confiscate the fish even though he said they could've. he took the fish home, and a few months later, went out of business.
Look around the LFS scene around my area, before, there were baby turtles with a not for sale sign, but if wink wink, you know the owner, or give them the right price, then you got a baby turtle.
Not anymore. no lfs around my area now have any type of baby turtles as far as I can see.
