Thanks for confirming that rape is less important than a man's reputation :) Women know that already. That's why many don't report.
Having seen people report rape in the US, it is certainly not enough for anyone to be arrested immediately. There's the question of evidence, and whether anyone will look at the evidence, and whether the victim can be talked into ignoring it. In 2013 there were about 20,000 untested rape kits in Texas alone -- 20,000 crimes that were reported, where a woman had semen, hair, and other evidence collected through an invasive procedure, that were entirely ignored [1]. And that's only reported rapes. None of my friends who have been sexually assaulted have ever reported it (although these were all assaults by "friends", not strangers). They just wanted it to go away.
To top it off, in many locations in the US women still have to pay for their own evidence collection. If you haven't got the $600-$1200 it takes to pay for the exams yourself, you're out of luck on the prosecution front! (Yes, this is sort of illegal, but it's still happening [2].)
So rest easy -- come to the US where a woman's statement will probably be ignored for a long time [3].
