Would really like GP's thoughts on this. Sounds like they were questioned but not indited, the thing which the cop in that video denies ever happened. It also depends on the country. Watching police shows in NL, everybody talks and it often really does matter what they say, e.g. for the police to believe whether that bicycle is theirs, or whether they get a contact prohibition to their ex (where someone has to make the decision whether their request is reasonable), etc.
Do heed what's mentioned in the video, it's mostly true I presume and probably doubly so for their country of origin, but also consider there exists a balance
