Tell me, is the rise in crimes with guns related it immigration (legal and illegal)?
I honestly don't know, but I'd be surprised if it is that significant.
It's hard to immigrate to Australia and we don't have a major illegal immigrant problem - it's a lot easier to secure borders surrounded by hundreds of miles of ocean than it is a long land border. We do have some crimes that seem to specifically involve some refugee groups but most of that seems to be knife crime rather than gun crime from what I've seen.
Gun crime really does seem to involve people who have been here a lot longer.
