There is but it's not appropriate in cases where police officers have probable cause to believe someone is in danger. Like I said above, police officers don't typically get warrants for stuff like this because it's established as permissible through case law and precedent.
If they were to back off and wait for a warrant (which doesn't happen as quickly as it does on TV...even with an on-call judge) and then the husband decides to take the entire family out with him, now who's at fault? That's right, you'd all be pissin' and moanin' that the cops didn't do their job.
So someone else can argue fruitlessly with Hound because he's obviously too dense to listen to reasonable and correct explanations. People like him are why gin was invented.
