The key point seems to be whether that behaviour was legally recognized as being criminal - i.e. they were convicted of a crime.
Not necessarily. While a conviction for crime involving violence is
prima facie evidence of violent tendencies and a firm ground for forbidding possession of firearms, it is not the only possible ground. Evidence of certain behavioral disorders,
plus evidence that the subject has exhibited violence tendencies, such as attacking or threatening another person, especially with a firearm, may also be grounds, even if no criminal charges were filed. What is not sufficient is the mere opinion of a shrink that the subject is dangerous, without any evidence that he has actually injured or threatened anyone.
Another issue is the type of firearms that people should be allowed to possess. As a general matter of principle, should people who have not previously broken any laws still be required to justify the reason why they wish to own a particular type of weapon?
Should we be required to "justify" why we should be allowed free speech? In general, behaviors that violate or threaten no one else's rights require no justification. What requires justification is restricting those behaviors, the presumption (in free countries) being that persons may live their lives in any way they choose, may do anything they wish to do, as long as they violate no one else's rights.
Or, alternatively, if I wish to own a weapon of mass destruction with no obvious self-defensive use is that my business and nothing to do with the government? Are my reasons for wanting to own such a weapon entirely a private matter?
No. Unlike personal firearms, weapons of mass destruction, if ever used, by definition pose risks to others.

I'd love to hear what you would count as evidence that someone has been "radicalized." Have passionate, strident demonstrators against Trump been "radicalized"?
What is a "military grade weapon"? An M1 carbine? A .45 cal. automatic pistol?
Persons should be allowed to buy and possess weapons because they have a natural and constitutional right to do so, not to "appease the NRA."
