If he's arrested and goes on trial here in Sweden it will make big news, there will be major coverage both by Swedish and international news media. I'm not that sure there would be a big risk of his being sentenced for rape or assault, that just looks too thin and lawyers here are not corrupt. Hopefully a trial on this would help put the laws on sexual violence here under the spotlight and make people realize they are much too easy to manipulate while they don't really protect women/victims either.
Last year a faculty professor of law here suggested that any sexual encounter that was made without, like, explicit (written?) formal words of consent should be possible to prosecute as rape, even a long time afterwards (this would have required a rewrite of the present law, but it's in line with how a vociferous part of the public opinion wants it). When people date or meet socially and get turned on, or even when teenagers are rubbing elbows, how often do they stop, suddenly look the other part in the eye and say, "Well. do you want to get fucked now? is it okay if I pump you, hun? Is that a deal?" That doesn't sound like what you would do, does it? Rape mostly isn't a 'smoking gun' crime such as robbery, where the proof that it happened resides simply in the material facts, the raw act itself: you can have two encounters where almost exactly the same things happen physically, even much of what's spoken is the same, and one is good and the other one is (to at least one of the involved people) rape or assault. The intentions, the understanding, the attention to what they want is what really decides it in their minds, but that isn't all piece of cake to show and decide many months afterwards in a courtroom. If it's defined as "rape is when the woman says it felt like rape, and the man should be seen as a priori guilty" it's anything but judicially secure, and that's how some circles here want to have it, want to tweak the law.
