I see these as hurdles to jump and not necessarily insurmountable. And this excuse about the US's culture needing to affect our laws is getting lame.....there are many borders in the world that have distinct cultures from one another.
To be clear, I am in favour of tight gun-control laws. This new announcement isn't enough, either. It's a half-measure that could, and should, have happened years ago.
But we cannot pretend that fixing our laws around gun ownership is going to make us free of gun violence. Gun control is part of a solution, not a solution in itself. We also need to stop the flows of black market weapons and deal with our urban gang problems.
