A multi-part package on loopholes and inconsistencies in the Canadian gun control system that I’ve been working on since before Christmas was published out today. It makes heavy use of a redacted copy of the national firearms database which we obtained under access-to-information laws before the long gun data was deleted.
The new parts of the package are:

• The lack of regulation of short-barrelled shotguns, which coexists with strict laws against sawed-off shotguns (which might well be longer)
• .50-calibre rifles are non-restricted firearms, the same status as mainstream long arms used by farmers and hunters. 464 are privately owned in Canada – I used a JQuery database to display them all.
• A workaround to the five-round magazine limit for centre-fire semi-automatic rifles.
