I can understand why they don't let Brits own guns.

BAN EM !!!!!!

Or, have background checks, and government programs to teach

murderers to not murder with knives,

and they will use something else as a weapon.

No, wait, just outlaw all knives, unless they are only a molded piece of soft plastic, only one inch long.

You don't need a steel knife to cut butter with....

they'll have boston stranglers all over the place, murdering a thousand a month with ropes.

Or, you could let decent people have ccw, and watch how the murder rate drops.
