I think the governer has done a good job beefing up security at TMI. However, one must remember that regardless of precautions taken, there is always a risk.
For people who say the plant should be shut down, consider this. Just how much energy that we in the Susquehanna Valley uses comes from TMI and/or Peach Bottom? How much would it cost residents in $$ if we had a situation like California - not enough power? And most important of all - would the residents be willing to pay for it without whining?
My opinion is that people who lived around TMI prior to construction beginning there have a legitimate issue. Those who moved there afterwards should really bite their tongue! They had a choice of where to move, and no one forced them to live next to a nuclear power plant. They made that choice for themselves.
Bottom line, no one is ever going to be completely safe. The state government is doing what they can to protect us (with guards, KI pills, etc). Once again, if someone is unhappy with the situation, don't complain and moan, do something about it - like MOVE!
