The Death Penalty is not an effective deterrent
-No Research showing that capital punishment deters crime
-Some data can be skewed by the people creating it.
There are a lot of studies claiming that the death penalty supports deterrence and there are a lot that say that it does not. (Berk)
These studies are flawed in many ways, so that we ‘can’t tell’ if the death penalty deters crime (Berk).
Data often includes murders that are not eligible for the death penalty (IQ or Age) (NAP).
We would need very precise data to determine if the death penalty is a deterrent, which there is no specific data. (NAP)
When all states are viewed together in data, it creates and aggregation bias. (UMich)
Two empirical papers have tested deterrence by Death Penalty. Both found no evidence of deterrence. (UMich)
COUNTERARGUMENT: Some data shows effectiveness as a deterrent (Penn)
Both, panel data studies and time series studies, have shortcomings when it comes to their statistics. (Nagin)
Most research fails to show a significant trend or pattern. (Bailey) .
The Death Penalty does not deter homicide, drug crime, or other smaller crimes.
The death penalty did not deter crime and life imprisonment was a more effective deterrent (Mitchell)
COUNTERARGUMENT: Death is a more effective punishment than life in jail. (Tucker)
Death-penalty states in 2005 had a 46% higher murder rate than states that had banned capital punishment. (Suggs)
The death penalty can only deter if the murderers know people are actually getting executed. Some people sit on death row their whole lives. (NAP)
There are 13 states where capital punishment increases murder rate. There are 8 states where it has no effect. (UMich)
Some people believe that the death penalty has a brutalization effect. It creates a more violent environment in the state. It sets an example of killing as revenge. (UMich)
Experienced Criminologists are less likely to say the death penalty is an effective deterrent. (Radelet)
Homicide rates varied a little bit but death penalty didn’t have an effect. (Choe)
People committing murder don't care about the punishment.
Many murderers believe that they have to kill their victim, so the punishment doesn't matter. (Tucker)
The death penalty can only deter if the murderers know people are actually getting executed. Some people sit on death row their whole lives. So the murderer might not think about the death penalty. (NAP)
COUNTERARGUMENT: "Death Penalty scares potential murderers". (Tucker)
A killer takes no remorse when they kill innocent people. They aren’t going to be deterred by the death penalty. (Sundby)
The "Deterrent Effect" wouldn't logically work
There were over 20000 cases of homicide or voluntary manslaughter average in the 1990s. Only around 50 people were executed each year. This small amount of executions would not produce a deterrent effect if the deterrent effect was true. (Bedau)
There aren’t certain people who deter crime, so in order to deter crime, we would have to execute all the people that committed homicide, which is impossible to do. (Bedau)
• The claim of deterrence is ‘dangerously delusional’. (Suggs)
Deterrence is believed to be true by many, but in reality it is not true. (Mitchell)
Deterrence plays a minor factor when the jury is deciding if they want to give the murdered capital punishment. The jury thinks more with their emotions than with the logic of deterrence. (Sundby)
COUNTERARGUMENT: Executing a murderer makes sure he doesn’t murder anyone again (Reams)
The Death Penalty shortens someone’s time in jail. How does this deter a crime from happening? Would a quick court trial also create less crime? (Crump)
