A log the victim ran over last week loosened the bolts.

The prosecution wouldn't even blink if you pointed this out.

Unless the perpetrator intended for that to be the effect.

Have you heard about mens rea?

It turns random logging into laying logs onto a road intending to harm someone with the foreknowledge that they will harm the target and as a consequence any other people traveling on that road.

Terrorism charges and straight to gitmo.
