Parallel construction is this huge phantom menace on the internet but something that in real life occurs less frequently than a person being struck by lightning.

Law enforcement faces a very high burden to show that parallel construction would apply. (Not "could." Would.) This generally requires law enforcement to show that they were pursuing multiple parallel paths of investigation, and that basic investigatory work in one of the other paths of investigation would have legally led to the excluded evidence as a matter of course. To put it perspective how difficult this is, a former co-worker that is still with the public defender has seen the prosecutor succeed exactly once in 15 years in making a parallel construction argument.

The DEA is the only agency that successfully makes parallel construction arguments on a regular basis, and this is primarily because the DEA has the resources to actively pursue multiple parallel paths of investigation, and because in many cases the reason for using parallel construction is that key witnesses have a tendency to get murdered....
