In situations like this, I think the person at the top of the chain that told employees to perform the illegal installations should be arrested and charged. On top of that, the company should be fined into bankruptcy. If the directors knew about it any companies they're involved with shouldn't be allowed to conduct future business in the municipality (or state).
Most likely the feds said they will tie up whoever challenges them in federal court. They can play jurisdiction fuck fuck games and then flip between it being a search, it being necessary for safety, that the city/county was obstruction a federal investigation, and all other nonsense.
Don't think your company could just put up cameras and post the location of LEO and they'd let you get away with something like that.
The keep saying this and losing in court. I don’t have much respect left for these bootlickers who won’t fight.
