I remember being excited when I was asked to use a sledgehammer to tear down a covered garage that wasn't approved by the city. It had been standing beside my girlfriend's house for years. You could tell it was built intelligently and with love. The supporting beams were twice as thick as required by code, and every nail and screw was driven straight. The lumber itself was top shelf, not a knot or bend in it.
I have a hard time driving a nail straight -- yet it took me less than an hour to turn the structure into a crumpled pile of lumber. In the security world, something similar happens every day when hackers tear down whole networks and systems.
