I'm not going to be able to do that. But I can propose that "criminal illegal ownership of firearms" is one of three avenues to gun related (non-suicide) violence- particularly when homicide is the objection
A- criminal illegal ownership - gang bangers etc. Gun control laws have no effect, and the government is not doing near enough for political reasons.
B-person that desires to commit violence seeks legal ownership
C-person with legal ownership desires to commit violence
I'll fully concede that in Canada A is the greater issue (and even then not a big one in the National context), but when we look to the South, we can see B and C become serious threats to public safety at the intersection of insufficient gun control and sufficient societal... angst? That angst level is rising in Canada. I wholly admit to being a fudd, but have been around guns all my life. 6-10 years ago I'd be fully against the need for any further gun control in Canada, and am in no way in favour of Bill C21 or the "assault weapons" ban. That being said, I can see the argument that the PAL (which can be passed by a reasonably trained monkey) is not a high enough bar to be the only thing standing in between increasingly disgruntled/radicalized/ scared / disenfranchised people and a modded Ruger Mini with no purpose other than the planned or hypothetical taking of human life, hence musing about the RPAL as a compromise to raise the bar on who has high capacity semis without all this ban nonsense.
