People think police are judges or prosecutors and (falsely) trust what they say accordingly. The police are evidence collectors for the prosecution, who presents evidence to a judge. Police are the lowest men on the legal totem pole and have little power in deciding the outcome of your case.
That alone should be enough to make you never trust whatever they promise, because really they cannot promise anything.
i sound like a conspiracy nut every time i bring this up, but wireless-networks-as-a-sensor seems unavoidable. there simply is no way to keep improving wireless transmitters without also increasing their environmental awareness and therefore leaking data about physical spaces. even simpler networks like wifi will dynamically adapt channels, frequencies to optimize speeds and it turns out you can extrapolate a lot from that [3]. advanced networks with features like beamforming are even more responsive to their environment and therefore more leaky. we're making accidental cameras, and they can see through walls.
it seems like this is going to be a "feature" of 6G mobile networks. read up on "joint communications and sensing" to find research in this area. (it's not just nokia.)

False confessions don’t just send innocent people to prison, they also close cases without finding the actual culprits.
Remember the police are incentivized to catch people, not catch guilty people. So the easiest way for them to game the system isn’t in society’s best interest.
Let's say you’re being held hostage by a dangerous armed criminal who has already harmed others and is threatening to kill you. The police arrive, and the criminal demands to know if there are snipers positioned outside. If the cop truthfully says “Yes,” the criminal might panic and shoot you immediately. Instead, the cop lies and says, “No, it’s just us talking, let’s work this out,” buying time for a sniper to take the criminal down and save your life.
There are lies that don‘t poison anything.
For instance police lies in an online chat to be a 12 year old girl to catch a child predator.
That’s still lying police just with extra steps.
That's a more expansive proposal than the law being discussed. The law is narrower than "investigating" and is focused only on interrogating a suspect, so presumably post-Miranda warning. And in this context being a "suspect" is a specific category elevated from being a witness or person of interest. And then the only penalty in the law is making a confession obtained as the result of a lie to a suspect during an interrogation inadmissable.
Those differences address the concerns mentioned downthread with lying in the context of undercover work.
Cops can lie to suspects during questioning. They can say "your friend already confessed" or "we just got a call from the lab, your DNA matches" or "you're getting the death penalty unless you confess right now". As well as bullshit like https://en.wikipedia.org/wiki/Mr._Big_(police_procedure) (in some jurisdictions).
I'm fine with undercover cops lying about whether or not they're wearing a wire, or your scenario. I'm not so keen on uniformed cops lying to elicit confessions.
This may be irrational, but I'm more worried about being falsely imprisoned by legal means than I am about being murdered by illegal means.
That's called "exigent circumstances", and a lot of rights are normally thrown out the window if that's the case - police don't need a warrant if threat of bodily harm to themselves or others is on the table.
And that isn't what most lying cops do is about - most of the time it is bad for the public.

Not as straightforward as you're implying.
A detective doing undercover work may require a degree of duplicity to achieve their aim, their authority as an officer is not what gets you to believe their lie, they almost always conceal that fact from you.
I think these are clearly distinct arenas of law enforcement.
reading some of the criticisms of their former behavior does highlight pretty strongly why exactly that kinda thing is problematic.
