Indeed, kids kill their parents at a rate of about 5 per week. That's 250 a year in the US. Your biggest risk to being shot is in your own family.

Very few people kill in general. According to
Wikipedia the murder rate per 100,000 inhabitants in the US was 4,88 in the United States. This pretty high for a country as rich as the States, but still it's only a small minority, 5 people every 100,000, that get killed in one year. Assuming that the rate stays the same in a human lifespan (approximated to 100 years) only 0.5% of all people in the US which are born today will be killed, and since the are more victims than perps, less than 0.5% of them will be killers.
The perception that we have of murder is highly disproportionate to its reality. You're
far more likely to die of influenza and pneumonia in the US than to be murdered, and you're still more likely to kill yourself than to be killed by someone else.
This isn't to say that murder isn't a problem that needs attention. After all we diagnose and treat all sorts of diseases, both common and rare, so it makes sense that we devote considerable effort to find out who killed whom, and to try to make sure that those people don't do it again. Murderers cause grief and pain in the relatives of the deceased, and fear and anxiety in everyone else (murders are a larger cause of death than diabetes, for example, and nobody says diabetes isn't a serious concern).
Similarly terrorism causes even smaller number of deaths, but it causes so much anxiety and fear to its unpredictable nature and due to causing mass casualties when it happens that OF COURSE we devote plenty of resources to fight it.
My point isn't to trivialized murder, but to point out that the vast majority of people AREN'T murderers. Murderers are an anomaly, not the norm, so it doesn't make much sense to try to blindly apply one's opinion of what makes sense and what doesn't as someone who hasn't murdered anyone to a murder. Indeed people devote considerable effort to find out what motivates murders, BECAUSE most people don't murder others.
True, you're more likely to be killed by someone that you know intimately (which includes family members) than by a stranger, but that's because a lot of murders are crimes of passion or of opportunity, and you're not very emotionally involved or have lots of access to complete strangers.
