It appears that gun homicide rate increased under Bush Sr. (~5.6 => 7.0) and Jr.(3.8 => 4.0), and declined under Reagan(6.6 => 5.6), Clinton (7.0 => 3.8) and Obama (4.0 =>3.6).
Numbers are in death/100,000 people, (+/-0.1 because they were read from the graph[0]).
A t-test on the yearly rate of change, yields a p-value of 0.002. (in Excel =T.TEST(A1:A12, B1:B14,1,3)).
Did the Bush have a peculiar approach regarding crime fighting?
