Inevitably the subject of Finnish gun laws has been brought up in the aftermath of the Jokela school shootings. This morning Prime Minister Matti Vanhanen weighed in:
Vanhanen said that the possibility that hand guns should be kept at sports clubs and target ranges, and not allowed to be taken into the home should be considered.
Other proposals I've seen include a requirement to undergo a psychiatric evaluation and an obligatory waiting time of a month or two before getting one's first gun permit.
Since the discussion is clearly motivated by Jokela, it's worth considering what sort of restrictions on gun ownership would have prevented this tragedy. For example, the proposed EU directive which would limit gun ownership by those under 18 years old - and which Finland used to oppose - wouldn't have prevented the Jokela shooter, Pekka-Eric Auvinen, from buying a handgun, since he was over 18.
Whether Auvinen could have passed a psychiatric evaluation is something I don't know; obviously if he was honest about his views and feelings, he couldn't have done so, but he might have had enough self-control to hide his problems. It seems to me that he got his gun specifically to carry out his murders, so he would have had a reason to misrepresent his inner life to a psychiatrist.
Having written all that, naturally law changes that couldn't have stopped Auvinen might still serve to save lives.
