My father used to work in electricity transmission, including some very long high-voltage DC lines. He said that a big problem they have with lower-voltage lines is people shooting at the glass insulators, and a big problem they have with the high-voltage lines is people shooting at the spacers... and also stealing bolts and straps for metal value. It's interesting to think about what could have happened if someone unintentionally caused serious damage to, say, a transmission line which was the largest connection into Los Angeles, but ultimately they are built pretty sturdy. This kind of vandalism is just a huge hassle for just about any infrastructure that covers a meaningful amount of land.
