The article didn’t specifically show other age groups but it did give the overall number which shows more disapproval, implying that older age groups found it less acceptable. It also links to the survey that shows the different ages’ break down:
The survey from Emerson College Polling found 68 percent of all respondents found the actions of the person who shot and killed Thompson unacceptable.
I think it might struggle when comments get deleted. And this comment chain is a bit of a mess start to finish haha
