For once I agree with Teribus. "No remission" is the correct verdict for one who uses a gun in committing a crime. There is no excuse. This is true with any weapon as far as I'm concerned.
When I served jury duty if I found out that a gun was used in the commission of a crime, my verdict was automatically guilty. That kept me off the panel in many cases.
If gun owners are not responsible in their use, then the guns should be taken away from them to protect the public. Responsible gun use such as target practice is a "right" but if the line is crossed, then the right should be forfeited.
The government has a role in the protection of the public by taking weapons away from criminal users.
