Logical Fallacy

In politics logical fallacy is everywhere, for this post I decided to watch a few debates and it didn’t take long for me to find logical fallacy. In the debate, moderator Maria Bartiromo asked Florida ex-Governor Jeb Bush the following:

Bartiromo: Governor Bush, gun rights… What is the harm in tightening standards for not only who buys guns, but those who sell them?

Bush: I think we need to focus on what the bigger issue is. It isn't law-abiding gun owners. Look, we have a reduction in gun violence because in Florida, if you commit a crime with a gun, you're going away. You're going away for a long, long while. And that's what we should focus on is the violence in our communities.

Jeb Bush is claiming that the fact that “youre going away” meaning you will go to prison “for a long, long while” if you use a gun to commit a crime in flordia caused the reduction in gun violence in the state he was the former governor of. The word “because” signals that this a casual claim. However, how do we know that. However, how do we know that the imprisonment policy is responsible for causing the drop in gun violence? Bush is not explicit about when this policy was adopted, but presumably it was adopted before and was in place during at least part of the reduction or it would be clear that the policy could not be responsible for the reduction. So for this reason I decided to fact check Mr. Bush’s claim that gun violence went down in Florida while he governed there. The Washington Post’s fact checker:

Some types of gun violence decreased while Bush was governor of Florida, but not all. … Overall crime decreased while Bush was governor of Florida from 1999 to 2007. The downward trend continued after he left office, and is consistent with crime rates overall in the country. This is not an exhaustive look at gun violence in Florida, but we crunched the numbers in three key categories of gun violence to see how they fared between 1999 and 2006…. Murders by firearm were at three per 100,000 in 1999, then four per 100,000 in 2006. But it increased to 4.4 per 100,000 in 2007…. Aggravated assaults with firearms and gun robberies went down while Bush was in office.



It appears that gun violence in Florida during Bush’s term was like a seesaw, some types went up and some types declined. The Fact Checker points out, the downward trend in Florida was part of a larger national reduction in crime. For this reason, it's impossible to know how much if anything "tough" sentencing policies may have had to do with this reduction. Plausibility is not enough.

  1. Hey, I'm not quite sure what the logical fallacy here is. It could be that correlation does not equal causation, but Jeb could also just be bad at understanding statistics.

    I think its really important to read into exactly what someone has said before making conclusions. Does Jeb Bush mean that because Florida has stricter sentencing, that crime is going down . . . or does he mean that because of said sentencing, crime in Florida is statically-lower than other states? From the quote, he can mean either or, though I lean towards the latter.

  2. It looks to be the causal fallacy ("because we have tough punishments related to gun use, gun crimes went down"--my paraphrase). But what is shown here is that that wasn't exactly the case. Once we move to the data, had Bush used a data point he might be cherry picking the data (another fallacy), but he could have made an argument. As it stands, it's often hard to decipher the strongest candidates in debates. They tend to veer off track very quickly. The irony here is that Florida is famous for letting those who try to use other laws, like "stand your ground" to allow gun users more flexibility and range in protecting themselves. Just think to cases like the Trayvon Martin shooting (in Florida, that law is very controversial; check out this article: http://www.miamiherald.com/news/politics-government/state-politics/article57127123.html).
