A certаin stаte (stаte 1) recently repealed its law allоwing juries tо seek the death penalty, while a neighbоring state (state 2) kept its death penalty. Kanwar is interested in seeing whether state 1's repeal had any effect on crime rates. He's interested in using a difference-in-differences research design, with state 2 as a control group. Before doing so, he creates the following graph of the crime trend in state 1 and state 2 before and after state 1's death penalty repeal: Based on this graph, will Kanwar's choice of using state 2 as a control for state 1 yield valid results? If no, what assumption(s) is being violated?
