if they can get in that easy, cracking a couple of transmission voltage insulators can could cause widespread damage that would take weeks to fix.
But then again, the ultimate fear if the SOB’s know what their doing, is shorting the transmission voltage to the downside of a substation transformer. I won’t describe the calamity, but let’s just put it this way: it would probably get more news coverage then say... 9/11
There will always be vulnerabilities in our infrastructure and it is doubtful that new federal agencies or hordes of new federal employees will fix it. This is the problem with our political leaders as we saw post 9/11. There only solution is new agencies, more employees, and spending more money.
I have said many times and I am sure most agree that we have been fortunate that AQ and our enemies are hyper-focused on the spectacular when they could bleed us to death financially (and emotionally) with lots of small low-tech attacks.
Government will naturally try to harden every target they hit, but the real danger is that government at most levels is already unaffordable. They could bring us to our knees if they were smart.
