Although the frequency of such irresponsible behavior dropped after Jefferson's expression of concern, it did not die away completely. Like many universities and colleges, it experienced periodic student riots, culminating in the shooting death of Professor John A. G. Davis, Chairman of the Faculty, in 1840. This event, in conjunction with the new UVA Honor System and the growing popularity of temperance and a rise in religious affiliation in society in general, seems to have resulted in a permanent change in student attitudes toward reporting the bad behavior, and thus such behavior among students that had so greatly bothered Jefferson finally vanished.
