Could you be more specific? It's really hard to have an useful conversation based on a comment like this, but really easy to have one based on a comment which links to specific cases and perhaps even explains how the obvious parallel construction appears.

It's a common "conspiracy theory" that this happened in the Luigi Mangione case even thought I don't agree he's "probably innocent":

The FBI apparently attempted to use this in the Bryan Kohberger case:

It's hard to find solid coverage of this because obviously the methods are often hidden and rarely leak out to the press at large. The press also gets confused and thinks that defending our constitutional rights will lead to criminals being acquitted.

If you spend a lot of time watching and studying these cases and how they evolve throughout the courts it becomes obvious that this is likely occurring more than most people realize.

		I don't think the Mangione case is a particularly good example, you wouldn't use a 911 call by a random McDonald's manager to disguise parallel construction. The caller is easy to identify, how could the government ever trust this person to not reveal their parallel construction? If they were planted by the government, that'd be extremely difficult to hide. The government also likely wouldn't be able to compensate them in any meaningful way for telling such a lie. The Kohlberger case also does not suggest parallel construction, the DOJ policy isn't binding and the DOJ can in fact legally violate that whenever they want.
