The options are you assume people are innocent unless proven guilty, or guilty unless proven innocent.
Going through life treating everyone as guilty until proven innocent sounds like an exhausting and negative way to treat everyone, and harms more people overall.
Those are not the only options, those are the two extremes of a spectrum. Most people fall in the middle with something like "assume people are innocent unless you see convincing evidence of guilt". This is a reasonable philosophy unless you have power over someone, in which case proof is much more important.
