Sorry, that was overly provocative and arguably unjustifiably personal. I apologize. The point is that the statistics do not back up many fears.
> And why did you pick "Assault by sharp object: 1,805" instead of "Assault by firearm: 10,801" or just "Assault: 16,765"?
The example was a 'stabbing rampage', that was specifically to try and find the number of knife attacks in the US resulting in fatality, and out of those number where someone is randomly attacking people in public.
Overall, we are still dealing with pretty small numbers whether it's 1 vs 5 or 1 vs 50 (50x improved chance of winning the lottery is still nearly negligible odds). In the case of knife attack, based on these numbers, it would be at most 1 in 5.
The ultimate point is the statistics do not back up many of these fears. For example in response to an actual knife rampage I observed a lot of chatter about getting a concealed carry permit etc.
These same statistics show that assault by firearm is way more likely than by knife, and having more guns around is more likely to have examples where they are used. Hence, the irrational fear of a knife rampage is prompting people to carry a gun, which then dramatically increases the chance of an accidental shooting in their own household, suicide, and/or assault where that person gets into a confrontation they could have walked away from but instead had road rage and shot someone else.
Household, accidental shootings are relatively common, and suicide is exceptionally common, yet all that seems like less risks for firearm possession compared to needing the firearm to actually protect yourself from a knife attack, which is at most 5 times more likely than slipping and drowning in your own bathtub.
In the case of a bathtub, it's common and does not have the same confirmation bias we get from headlines of rampages, yet it poses a fairly similar danger to you as someone going on a knife rampage.
