Perhaps Oystein can tell us how much more likely it is for 9/11 truth supporters to be murderers compared to normal members of society.?...
No, I can't, and I wouldn't dare to.
We can get overall homicide stats.
But how do you decide how many homicides were committed by 9/11 Truthers?
How do you decide how many 9/11 Truthers there are in the general population?
Could you count all those who ever, anywhere, have published an opinion on 9/11 being an inside job? Online on blogs, fora, guestbooks, or real-world in demos, letters to editors, interviews?
AE911Truth seems to have reached ca. 0.04% of all professional engineers in the USA - 1 in 2,500.
Probably a higher percentage of licensed architects.
Extrapolating from there, I'd say that at least 0.1% of the general population (1 in 1,000) might be ready to publicly lend their voice to demands of a new 9/11 investigation.
Truthers of course will claim that they have a majority of the people.
If Brainster's list is legit (I haven't checked). we have 10 victims of twoofy American (?) murderers (?), with now over a span of a little over 11 years, or 0.9 per year.
Scanning WP's
https://en.wikipedia.org/wiki/Homicide_rate I find a number of 14,748 murder cases in the USA in the last reported year.
So it appears that the at least 1 in 1,000 truthers account for 1 in 16,000 murders.
Given those numbers, one would conclude that Twoofers are much
less likely to murder than other people - but of course these numbers have holes larger than the twin towers.
