Countries that have strict gun laws have far fewer incidents of gun violence. There are ample statistics to prove this.
Fewer than what?
Fewer than they would otherwise ?
Austrailia had little gun violence, then after a massacre much like this one they came up with very strict gun restrictions, then like majic, they had little gun violence.
There really are not ample clean unprejudiced statistics to prove this.
By carefully contaminateing the stats you can get qhatever one wants .
At Columbine no leagally obtained wepons were used, someone who is plotting like this isn't handicapped by a regulation that makes it hard to move a gun leagally.
What most of these massacres have in common is a gunman attracted to a helpless population "protected" from haveing any guns themselves.
