Although I don't think it's official, I know some police departments encourage community members to do Craigslist-type sales in their parking lots. It's not escrow, but I think you'd have to be very bold to steal something in view of police surveillance.

Localethereum provides escrow as a service, but for trading ether. I've had good success with them so far, but I haven't had a transaction yet that's had to go to dispute resolution.

Yes. Localbitcoins does escrow.
