I've sat back and observed this thread as I have over 32 years in the electric utility industry. All electric utilities are concerned about electricity theft from a revenue AND safety standpoint. Who is and isn't prosecuted is another matter. It depends upon the local statutes. Some utilities and their respective legal jurisdictions work more at this than others who may not see it as important as other things in front of them. One of the most successful units I saw worked with the local legal system, and had changes to the ordinances (to be more specific, to deal with the severity of theft, and to deal with repeat offenders). Then, to top it off, members of the 'current diversion group' were deputized! Needless to say, there were a lot of prosecutions with a high success rate.
OK... let's get back to repeaters! :) 73, Kim - WG8S
