If the police witness someone murdering another person in the streets why can't they execute them there and then in states that have the death penalty? Wouldn't that save lots of time and money for someone who will eventually be executed anyway?

In most U.S. states that have the death penalty, executions must take place in a state-sanctioned facility and according to specific rules. This is for the safety of the executioner as well as for ethical reasons, to ensure the person is treated fairly and there is no possibility of error or misconduct that could lead to an unfair outcome.
