Unfortunately, that is not how the legal system works. As much as the legal system, in our country and many others, has its failings, it is fundamental that an individual is innocent until appropriate and convincing evidence that proves otherwise has been produced and evaluated by individuals with the appropriate competences. This, unfortunately, is not the competence of masses of individuals who have seen only a portion of the evidence (as reported by multiple sources, forgetting rhe semantics of material and/or evidence) available, have it provoke a strong emotive response (which is also reasonable considering the sort of topic), and arrive at an unwavering and unequivocal conclusion (which may be correct, but may also not considering the amount of phrases we are dissecting in an attempt to extrapolate information and arrive at a conclusion that supports our own individual opinion and bias).
To play devil's advocate; if context is not important, if I am casually arguing with my sibling , or loved one, or whomever, and state "oi, "fill in name here", you're doing my head in now, I'm going to kill you if you carry on" (the sort of phrase that many of us will have used at some time in our lives), is that sufficient evidence to say I have threatened to kill my sibling? Or would it matter that said recording then continues to capture us mocking one another for a few minutes before hugging it out? It is a banal example that is in no way comparable to the severity of the situation and evidence here, but highlights the importance of context and I personally believe it to be naive if one believes that it shouldn't be the case
I often fear that a society that is governed by overall public response on social media and within the (the often, quite frankly, downright abhorrent) media is a slippery slope to be going down, especially if we ever arrive at the point where we are governing based upon "assumptions".
