In April of last year, unknown individuals destroyed an electric substation near San Jose, California. Telephone lines were cut and snipers shot holes in the coolant system, causing the transformers to overheat.
The destruction required professional knowledge of telephone and electrical systems. No one has claimed credit, and no one has been apprehended for the crime.
The San Jose attack appears to have been a live fire rehearsal for an act of war whose date is unknown. Owning a small auxiliary electric generator might not be a bad response.
