Bringing charges is not evidence.
Sigh - you can't trust cops even with physical possession and cameras rolling [1].
On July 24, 1973, Dallas Police Officer Darrell L. Cain fatally shot Santos Rodriguez, a 12-year-old Mexican-American child, while interrogating him and his brother about a burglary. Cain shot Rodriguez while conducting Russian roulette on the brothers in an attempt to force a confession from them.
In fairness, that was the 70s. But the 70s were also "one generation ago," so it's not exactly ancient history.
(I could imagine myself being skeptical about your comment before having wised up a little, so I thought I'd chime in to say yes, this really does happen.)
In UK we've been putting innocent people in jail for 20 years, because of bugs in accounting software. It was going unnoticed and noone would believe them untill recently. We are talking hundreds of people.
If it happened to a single person, noone would ever find oit the truth.

Note that in Britain, following a Tory amendment to the law, you can only get legal aid if you have assets less then £37.5k -- so if you own a home, and are charged (incorrectly!) with criminal proceedings, which you then win, expect to sell it to pay the legal bills. Once you win, you'll get...nothing. No fees. Just a "release the defendant from the dock" and you're good to go. If you get imprisoned, and THEN are found innocent later on, maybe, say, 30 years later (as has happened!) expect to get....nothing. I really recommend "The Secret Barrister" both as a book and a blog. Nobody stands up for funding criminal justice properly -- because what politician wants to support the rights of the accused? -- but it's badly breaking. https://thesecretbarrister.com/2016/02/02/mr-gove-must-now-h...
We should always presume innocence when law enforcement makes an accusation.
