There is a common sense aspect that seems to be missing here. While there may be 1 precedent setting case, the law itself has not changed to reflect it.
If there is a situation and your storage practices are investigated, showing the RCMP that you have something called a ‘safe’ that is heavy, with big locking lugs will probably end the discussion. Sure there is some grey area here, but when I shop, seems the difference between cabinet and safe are pretty clear.
Showing them that you have a lockable ‘cabinet’ or metal container and no trigger locks on your pistols, will most likely not end the discussion. Sure, you can pull up the 2011 case on you smart phone, show the officer and plead your case, but he is not in a position of discression. He will apply the law as it is written, seize your guns, and charge you. Sure you can appeal, then plead your case, have your lawyer raise the 2011 precedent and maybe even have the satisfaction of winning and coming back here to gloat. But you will have paid a hefty financial price and lost access to all your firearms for years. And it would have all been avoidable.
While principles and precedent are important and fun to debate, they don’t always trump pragmatic realities.
