There's a great lecture by a law professor on YouTube called "Don't Talk to Police". Watch it for some great insight on this. A key concept to understand is the phrase "Anything that you say can be used against you." That's a key phrase because of what isn't stated -- that words you say will be not be used to help you. A prosecutor has broad discretion to prosecute, and can (and will) cherry-pick information to use against you. Most cops and prosecutors are great people to have a beer with, and are not corrupt. But sometimes their position gives them a myopia and they see things or make connections are convenient or expedient. They are also invested with powers that make them extremely dangerous to interact with in many scenarios.
