At the risk of taking away the wrong lesson: the man certainly knew how to modify the hell out of a bulldozer.

The best thing he did that day was shooting himself.

I lived in Colorado when this happened. It got stuck in the basement of one of the buildings he was ramming the thing into. He lowered that cement cap down on top of the bulldozer. He knew he wasn't coming out of that thing. The air is thinner in those mountain towns.

What is interesting to read is that they had a helicopter with a missle that could have stopped him, but realized the damage from a missle would have been far greater than what he could do in a less that 10km/hr bulldozer.

So they just followed him around and let him have his tantrum like a child until he inevitably got himself stuck. I doubt you would see that kind of restraint today in the US.
