You can keep your mouth shut without a lawyer!Well I may be wrong, but I believe odds are weather a good shooting or not you're going to be arrested and the situation will be investigated. I would want to be represented by an attorney so I can keep my mouth shut and not say something that could be used against me in the future.
Lets look at the extreme, George Zimmerman, I think he made several mistakes but initially it was called a good shoot, than after public/political pressure a bad shoot, and his butt ended up with one hell of a bill.
Even if it is a good shoot, you may go bankrupt defending yourself in a civil suit. It may be a good shoot and still you are charged and arrested. Lawyers aren't cheap. Very good lawyers are exorbitant.I don't see the need for it. If it's a good self defense shooting, then there will be no insurance necessary. On the other hand, if it's not a good self defense shot...well then you're probably going to jail and insurance isn't going to do you very much good in there. Am I missing something?
