We had our own version of the VT massacre back in 1996 when 35 people were shot by a madman with an assault rifle in Tasmania. The result was a ban on automatic and semi-automatic weapons. Gun deaths fell from about 500-600 per year to 300 today.

In several Asian countries (including Singapore, Malaysia and Thailand) anybody convicted of committing a robbery or other crime with a firearm receives a mandatory death penalty.
