My Lords, this seems to be a matter of straightforward common sense. When there is a history either in which people have been involved in violence or which suggests that they may not always be in full command of their activities, because of alcohol or drug misuse, those are exactly the sort of people who should be denied access to firearms. The cases cited about firearms being used in domestic violence situations are a particularly compelling example of why this is important.
While I accept that chief officers of police must use their judgment, spelling out in legislation in this way that these are the matters they should look at, and that the presumption should be one in which they would refuse a licence application, is exactly the right way round it. That would then place the onus on those seeking the licence to demonstrate why they are suitable, notwithstanding the history of violence they may have shown or the fact that they were known to have substance abuse problems.
It is also extraordinary to hear from my noble friend Lady Smith about the difference in fees for various sorts of licence. This is surely an example where the fees should be set to reflect the fact that the checks which should be done should be thorough and all embracing, and should certainly cover the matters outlined in this amendment. On any common-sense interpretation of what Parliament should be doing about restricting the access to firearms of people who might be a danger to others, this is exactly the sort of amendment that should be put forward and agreed.
