If I feel that I might have to take a human life. I would use a Glaser Safety slug. It would help protect innocents behind walls in the same building. But they would be extremely bad for the bad guy.
I run Win 2K, and Norton Personal Firewall. I have never had an undetected security threat from Microslop,(soft, sorry), or from anyone else. When you update your OS read the EULA carefully, they state there that they are identifing your machine, not you, but your machine. And that no "personal Information will be collected." ME is a lousy OS. Shell out the bucks for a new OS, reformat, and enjoy.
If Israel was turned loose, there would be no "Middle East." Their people have been persecuted by regimes in Europe, and the middle east for centuries. They are able and willing to fight not only for their own country, but for what is right. While I personally hate their tactics I respect them.
