In the US, it's "innocent until proven guilty".
Media is so quick to assume the person is guilty just because of an allegation.
Of course innocent until proven guilty applies but the justice department knows that and still brought charges. At the very least, they believe they've proven beyond a reasonable doubt his guilt.
High profile cases with public pressure change the equation a bit and can cause charges to be brought on people who normally would not. I suspect this is a way to pass the buck to the courts when the person eventually gets off due to lack of evidence.
No, if following general DoJ policy, they believe that the evidence is sufficient that they will be able to prove the charges beyond a reasonable doubt, but that's not the same as them already having proven that.

Usually, I think the opposite is the case: generally, the DoJ is more careful in high-profile cases, not more cavalier.
