Hope you enjoy being on a watch list for that asshole comment.
US Presidents Assassinated is what I was referring to. I wouldn't be surprised if I was added to a watch list, but it's hardly an asshole comment unless it's also an asshole comment to mention our school shooting problem. The big difference is the scale of possible targets and the relatively probably of an attack. To that end, it sounds like on average
about $800 million (in 2008 dollars) is spent per year to guard the President.
Even with that sort of money, they still failed at least 3 times. Given the exposure, it's not too surprising. Also, notice that nearly every modern President has been a target, although that might just as well be the ease at travel today. It'd also be absurd to offer that level of protection for every school. In truth, money would be better spent on the
many other areas where children die from car crashes, drowning, and asthma. There's also congenital issues (for ages 1-4) and cancer and suicide for 5-14. Doing some math, based on
CDC information it looks like the death rate for the children by homicide by gun is maybe ~14%? There isn't a good overlap of the homicide by gun 1-17 range and the listed CDC data (the report is more about differences than raw numbers for subgroups). In any case, the bigger death by gun risks seems to be the 1-4 range.
tl;dr If you want to look at the stats and not just go off my sarcastic comment--which was more moral indignation about how we treat one man over all children--, the Secret Service is probably a good investment because of the cost of dealing with shuffling people around to fill the role and generally the loss of confidence of having one's President assassinated. One could argue, possibly, something similar about school shootings. If we're really just concerned about children's lives, though, we should focus on better child restraints in cars, more research into cancer treatments (actual cures, not simply stuff that combats it), and more resources to mental health to reduce the suicides. Oh, and pool covers.
