Well speaking of stupid, generalized comments like this are overtly ignorant. I mean instead of the daft rhetoric you just spewed why not look up the fact that even with this daunting sensationalized news, something your nation is very famous for you'd find the underlying truth. The reality is that even with what is shown homicide rates among children is significantly down and the likelihood of being killed in such a manner is 2%, if you'd like more info the CDC has nice flow charts and summaries for even the most general of sorts.
I'm not sure if I understood your rant correctly...
Sounds like you're saying school shootings aren't shocking events? Have Americans become that desensitised to School shootings that they are now just an acceptable statistic?
The statistics below show that these sorts of events are on the increase, which should tell you something given US murder rates have actually fallen over the same time period...
1991 - 1999 34 'school shootings' 70 dead
2000 - 2009 40 'school shootings' 82 dead
2010 - 2013 46 'school shootings' 61 dead

Surely society should do
everything within its power to protect its children from these sorts of acts?
The reporting of these type of events on British news channels (BBC/SKY/C4) typically adopts a sad, reserved and respectful tone. The 'sensationalized' news is reserved for celebrities and politicians private lives in the news papers - not unlike the US media.
More broadly, although the murder rate per head of population has declined in America over the past 10 years, it still has a one of the highest murder rates per head of population of any developed country - 4 x UK, 5 x Germany and 12 x Japan, for example. To think this has nothing to do with the culture of gun ownership is ignoring reality.
Ultimately, where do you think your society will end up if the answer to people getting killed by guns is we need more guns?
