I'm a man prone to stats and all for calculated safe decisions but there is a difference between planning the safest life for your family and actually blaming victims. Anyone saying they were asking for it by living in a Makom sekana would probably also blame a battered wife for standing up to her husband and him killing her in response or a half naked girl getting raped. The response should never be to blame the victim, ever, even if the victim statistically raised the odds of the negative outcome ocurring. There is always someone with greater share of the blame- the actually freakin perp. My $.02.
Need to focus on blaming and defeating the true enemy here. Now to insert some of my personal philosophy these animals aren't true animals which have no free will (rambam) but indeed have free will- they can be held responsible for their actions. God didn't do this to us these monsters did.
Also while hitching is unsafe, it's probably safer than in the US. It's part of the culture there and not at all out of the norm. Kidnappings through hitching aren't exactly common there afaik. Just an anecdote but I had a friend who went to the yeshiva in gush for a few years who told me he hitched from that same spot hundreds if not thousands of times.
