For purposes of deciding where money and resources are best spent, I don't think it makes any difference whether there was someone with intent to harm or not.

For purposes of deciding where money and resources are best spent, I don't think it makes any difference whether there was someone with intent to harm or not. You can spend money to construct safer railway crossings, you can spend money to hire more cops or NSA operatives, you can spend money to educate cops, or you can make rule that all cars must have safety devices that stop them if they intend to cross railway when a train is coming, which will make cars more expensive, and so on and so on. Never the less to prioritize these, statistics are important.
