Apart from (parts of?) the US - most civilised countries have strong rules against entrapment. It's eg unlikely the first twin tower bomber could've been found guilty, as FBI initiated the plan and provided the explosives.
That doesn't mean police can't do "minor" entrapment in order to roll up a big case; it just means they can expect to sentence people for those acts.
As for a litmus test, I believe maiming or killing bystanders would qualify against most police officers (the trick, then is to make sure the "victim" isn't a carefully placed undercover asset...).
Now, assume a ring of human traffickers have the rape and killing of a victim as part of the initiation process: are there circumstances where we would condone branches of our government to participate in order to bring down such an organisation? I lean strongly towards no; but as has been seen from Japan under us administration to kfor in Kosovo - using war criminals and military/intelligence personell as part of heinous organised crime is a feature of our current world order. How do we fight it?
There certainly is! The bar is quite high though; it's not enough for a police officer to have given you an opportunity to commit a crime, they really have to have tricked someone into it who wouldn't reasonably be expected to normally commit a crime.
