I think it comes down to intent and use.

There's nothing wrong with security procedures.
I'd be all for releasing big scary tarantulas and scorpions into the cases overnight if someone wanted good little watch dogs.
The problem I see is if there's Big Bro legislating it to shops and shows as a requirement.
Then there's use. What do they intend to do with the recordings?
Are the BigBro Cali going to use use for a registration like they did a while back with the rifle requirements?
