With how prevalent parallel construction has become it seems obvious that any encryption backdoor would be immediately exploited as soon as law enforcement had even the slightest justification to poke around. If they find something, you can be sure they'll come up with a legal way to arrest you for it. If they find nothing, oh well, better luck next time. Not like you'll ever know they were even there (probably).

Do you have a good reference for more info on parallel construction?

Stingray manuals and law enforcement license agreements are strongly worded to require parallel construction. Start googling from there and discover a whole world of tinfoil.

No not really, as its more something I've read about on/off over the years, in a variety of articles, and I am by no means an expert.

The wikipedia article on the topic does have some decent links to specific examples from reputable sources and is probably a good place to start - https://en.wikipedia.org/wiki/Parallel_construction

Look at news stories of unusually large narcotics busts attributed to a random leo pulling over a car for a traffic violation.

Those cases suggest to many people that the end justifies the means.
