They are just trying to make it safer, keeping people honest. It is a tuff job and too many want to race around to were they are going. A lot of dumb drivers out there.No, they're still a PITA when they disrupt the flow of traffic during peak commuting hours, marked or not.
There are laws as to how much of the city income can be from tickets.
Maybe not the unmarked impeding but the speeder or reckless driver that is the problem.
None, both are ambushing tactics.
Don’t break traffic laws and then no worries
next question, how is it an 'ambush' to catch people breaking the law? It stands to reason that a cop would struggle to know if any car was 'slipping' or habitually breaking the law (unless they had some way to track that car for an extended period of time). So absent a method for determining intent, how should we police habitual speeders (who might otherwise simply temporarily slow down when they spot a marked police vehicle in plain sight)?
I’m running an unmarked personal vehicle. No plates or tags. That way the police can’t run my plates and therefore they can’t pull me over. It’ll work 
The problem isn't whether I'm breaking the law or not and whether I "deserved" to get pulled over.
If you're gonna say, "just don't break the law", and I say, "OK I won't", then what should I think is going on if I get pulled over by an unmarked vehicle since to my knowledge, there is no reason for me to be pulled over. I'm wondering who is it.
When unmarked cars are used to pull people over for traffic issues, the door is open for anybody with a flashing light to pull people over. Traffic stops should only be made by marked units.

Understand, I don't owe you answers or a debate on the topic. If you feel enforcing the law requires you to act like a predator to get the job done; then there is a significant lapse in your training and/or ethics. I would recommend reaching out to your supervisor or union rep for more resources, training or alternate employment.
Understand, discussion seems to be a very important part of internet forums, but if you don't want to discuss the topic i certainly wont be bothered in the least.
And i'm not a cop.
But you still haven't explained how these tactics actually 'pray' on anyone. If it's a safety matter because someone might pretend to be a cop, that is certainly worth discussing. But waiting to catch someone breaking the law, however they are setup to do it, doesn't seem to make them predators. But if you care to explain the thought process i'd love to explore your insights on the topic.
Is using aircraft to enforce speeding laws predatory?
