It depends on what he did.
For example Penal Code section 593:
“Every person who unlawfully and maliciously takes down, removes, injures, interferes with, or obstructs any line erected or maintained by proper authority for the purpose of transmitting
electricity for light, heat, or power, or any part thereof, or any insulator or crossarm, appurtenance or apparatus connected therewith, or severs or in any way interferes with any wire, cable, or current thereof, is punishable by imprisonment in the state prison, or by fine not exceeding one thousand dollars ($1,000), or imprisonment in the county jail not exceeding one year.” http://law.onecle.com/california/penal/593.html
I did not look at the video to see what he did.
I don’t see how he can keep his job unless they come up with some kind of psych. defense for him or his wife claims to have done all the damage.
