I don't think you just walk back in and chill in any case of this scenario upon getting rid of such vermin. The place is likely trashed, your possessions are likely fucked up.

It sounds like six months were burned on getting an eviction authorization. So the competition here is six months.

Can the cops get over with their "crime scene" needs within six months? If so, this looks like a winner to me. At least in this option they're immediately removed and go straight to jail. Not six months more of this free-loading bullshit at your expense.
