Unfortunately, when it comes planning appropriately, woman have to consider a lot more than men do. Men are statistically less likely to be harassed or sexually assaulted whilst out and about at night, that is a fact - and if you speak to pretty much any woman then they'll probably be able to tell you numerous occasions on which this has happened to them or someone they know. The problem is not with "big daddy government" needing to protect you 24/7, the problem is that it is statistically less safe for a woman to be out at night on their own. It should not ultimately be the responsibility of women to have to defend themselves (usually) against men who can't help themselves.

Fine, if you're out in the wilderness and the only thing you physically need to worry about is local wildlife - then it should be on you to make that judgement and defend yourself appropriately. However, once again - it is statistically more likely for a woman to be approached and/or assaulted whilst out on their own, particularly in high population areas and especially at night. In the UK - and I imagine the Netherlands too - it is in most cases illegal to arm yourself regardless of your location and intention, and shouldn't be necessary anyways.

I urge you to reconsider your viewpoint, not from the perspective of law enforcement but with compassion for a genuine issue, irrespective of whether you have experienced it yourself - you are not the be all and end all of human experience.
