I think we fall into a false sense of "How could this happen and no one get caught doing it". I know I've had that thought for decades now but murders keep happening and people keep getting away with it. I find myself thinking "Wow, I guess that was easier than I thought it'd be (thinking back 1-4 years), but _now_ it would be harder", the issue is I've had that same thought almost every year so clearly my guess of how hard it would be is way off.
