Today marks the 25th anniversary of The Dunblane massacre which took place at Dunblane Primary School near Stirling, Scotland, United Kingdom, on 13 March 1996, when Thomas Hamilton shot sixteen pupils and one teacher dead, and injured fifteen others, before killing himself.
Within 2 year the British government had effectively banned all private ownership of firearms by private individuals, other than those held at licensed gun clubs.
The UK has never had a school mass shooting since.
Conversely
In the past 10 years in the USA there were 180 school massacres, this number however counts only mass shootings that is school shootings where more than 2 people died, there is NO official record of how many shootings happened where no one was killed, the number of shootings where only one person died (regardless of wounding) is highly debated as some count only shootings where the person died immediately, or on the premises, while other count those who died up to a week later. Those who died from injuries sustain in th shooting but died more than seven days later are considered unrelated to the shooting.

It seems 17 UK children's lives are worth more to the people of the UK, than over 1000 children's live are worth to the people of the USA when compared to their fevered lust to continue to remain armed to the teeth in their own homes.
