Why would the residence need to be cleared? Why would the GF need to be restrained? They were investigating a noise complaint. They don't clear a residence for a noise complaint.
I suppose after you murder someone, it might be wise to control people that might retaliate. The only legal reason would be crime scene preservation. Of course, that would mean you need to make sure the suspects don't contaminate it. (The two cops would be the suspects)
See prior response.
The only potential legal justification I could see is some jurisdictions require officers to enter a residence in the event a domestic dispute is reported. This was reported as a domestic dispute, not a noise complaint, although based on what we know about the caller's comments it sounds like he wanted to call in a noise complaint then switched to saying it was a domestic dispute in order to "get the police there faster."
That potential justification is also very weak at best, and I don't know if that law even exists there.
