The other commenter says that gun ownership among people is on the rise yet I'm worried that such statistics could be skewed by selected people owning multiple guns.

You're right and this is what I'm actually scared of. Unlike the past, they don't need to cast a wide net and hope it catches someone. Today's tech allows for pinpoint accuracy with data and would allow them to act in such a way that all cases (i.e. abduction, kidnapping, arrests etc.) look like one-off cases to the public.
