I agree, it's NOT unreasonable to be concerned. If someone took matters into their own hands, and shot an elected representative, they are, in affect, denying the people who elected said representative their voice.
HOWEVER. I try to always view things from both sides, and here is my take on this. There is a LOT of anger in this country, because every single election cycle, we keep ending up with more of the same. With the advent of the internet, I think our population is becoming more and more aware of just how bad things are starting to get, in terms of political corruption, scandals, blatant lies to the american public, and in general, the fact that it seems our representatives act in their own best interest FIRST, and ours as a DISTANT afterthought, and ONLY if the two coincide. It not their goal to make american a better place to live, anymore. Their primary goal is to retain their seat in the office, secondary seems to be, more and more, to make money, via kickbacks, money laundering, drugs, and public office perks. And THEN they consider acting in the best interest of the people of this country. And it seems that our voices are being taken away from us, both in the form of a lack of viable options for government office holders, but also in the form of monetary values being the major decider in winning or losing a race, both federal, AND local. When this happens, what are we to do? What are out most effective, viable options for affecting a change that will result in a freer, better represented society? There are no redresses of grievances anymore. Every try calling your senator? Or sending an email? I have. Useless.
"We petitioned, we demonstrated, we sat in. I was willing to get hit over the head, I did; I was willing to go to prison, I did. To me, it was a question of what had to be done to stop the much greater violence that was going on."
That violence he speaking of was the Vietnam war. But now we face another, altogether different kind of violence. Economic violence. We are getting squeezed, both by taxes, and by the .01% of wealthy that rule this land. What would you have this man do, and others like him?
