Strict gun control in france.

[Thumpalumpacus]

Exactly. When the perpetrators are motivated and work as a team, laws, any laws, are easily subverted.

Then what use are gun laws?

I'm guessing it has to do with lower per-capita murder rates, as spelt out above. You might want to read that post.

While you're at it, you might want to read, and perhaps answer if you're not too tired, my first post in this thread.

Finally, let me just say that your putative argument falls afoul of the guideline of let not the perfect be the enemy of the good. Simply because a law doesn't eliminate all acts it outlaws doesn't mean that law should be stricken.

I'd suggest that you start thinking without allowing your agenda (obvious as it is) to be your mental filter (again, obvious).
