Should people who commit crimes with guns have their trigger finger amputated?

In the UK sticking two fingers up is a general "fuck you" sign similar to the American middle finger. A popular Urban myth is the French would chop the fingers off captured archers and so before battle the archers would raise them to show they still had them. It is of course total bollocks but it has given me an idea.

If people commit crimes with guns should we chop their trigger finger off? This would make it difficult for the them to use a gun in the future as well as acting as a visual reminder to behave.

I don't just mean murders, I'm referring to all crimes.
