> The presumption of innocence is a legal principle that every person accused of any crime is considered innocent until proven guilty.

That should be "considered innocent by the legal system". People are still free to come to their own conclusions--and act on them--even without a jury rendering a verdict.

Rather famously, for example, OJ Simpson was acquitted by a jury of murdering his wife. But most people these days would agree with the statement that he murdered his wife.
