It should be the responsibility of citizens to learn and understand their due process rights not for law enforcement to have to tell every criminal how not to incriminate themselves.
If someone can’t go on google and read the 5th-8th amendments before going out and doing some dumb and illegal shit then they deserve to be clueless thinking they have to answer questions during interrogation and be dead in the water when their trial comes.
Its easy to search “Do Americans have the right to a lawyer” on google.
TLDR: Knowing and understanding your rights should be the responsibility of citizens not cops.
It does though, and it happens all the time. Many people will offer false confessions because they think the police have constructed a viable case against them and it is simply their least bad option to hope they cab get out of prison a little earlier.
They’ll also gaslight, manipulate, or torture people into confessing. It’s really fucked up.
