That requires money and political will. In the absence of both, the problem everywhere is the balancing of the rights of the accused with the need to protect the unquestionably innocent and often vulnerable. After all an employer can fire someone sexually or racially harassing other staff without having to prove it in a court of law (unless the employee sues, and even then as I understand it civil law everywhere is based on probability, not nearly as high a benchmark as criminal.)
And we along with most Western nations also have that 'innocent until proven guilty' thing (which I think sometimes your country forgets, I have heard commentators saying the US is the only one who does when you didn't even
invent it

) so I and most folk here are at all not ignorant of it.
But people are also arrested and held pending trial - which can take months or even years - for serious crimes, yes? Again, need for balance in an imperfect system, which will never
not be imperfect because it deals with people. And people will never
be anywhere near that which is why the cliche 'court of public' opinion doesn't and cannot ever be expected to hold to judicial standards.
