All these problems with identity theft would be cut by over 90% if the burden of identity theft was on credit issuers rather than consumers. See how quickly credit card issues are dealt with for an example.
I can see using eminent domain to build fence. However, it is a crock that govt does not have to buy all the property that gets put south of the border, unless owner is allowed to put ladders on that fence...
This is the same gas that was in the circuit interrupter that failed in the 500,000volt (phase-phase, delta) substation arc video. It sees extensive use in the electrical industry as an insulating gas. Its neat stuff, but alas expensive and ozone depleting.
That particular line is a 94 mile 500,000 volt line between Hoover Dam and the Lugo substation near L.A. An SF6 circuit breaker had failed, it was carrying the 33.3MVAR line reactor magnetising current for the test. ~100amps. The line carries ~2,000 amps under load.
Somewhat, its really a book about welfare fraud.
