Why don’t you use an OUT command on the hidden sleeve?

There is nothing wrong with OUTING a dog from a hidden sleeve if the dog is clean in the OUT. If there is any question about a police dog re-biting after its release then it is too dangerous to out him unless he is on a leash where he can not bite the helper in the leg or body. If the dog gets hooked up and the handler has taken the slack from the line so that he can control his dog after the OUT there is nothing wrong with this practice.
