Gun control

Once again we have a situation where apparently the owner of a licenced firearm has used it to kill people.  I am ever minded of the TV comedy series "The Thin Blue Line" where Inspector Fowler (Rowan Atkinson) explains why he has never approved an application for a gun licence.  I can't remember the exact quote, but it goes something like "The first question on the form is - do you wish to own a gun? And anybody who answers 'yes' to that is clearly someone who should not be allowed to have one".  Many a true word is spoken in jest!
