Putting on his gun policy expert hat, Webster said he felt the laws are a "very bad idea," and they don't do what they were intended to do: deter criminals and protect the citizenry.
After Florida expanded its so-called "Castle Doctrine" laws to a Stand Your Ground provision in 2005, the National District Attorneys Association released a report.
It said a "diminished sense of public safety" after 9/11, a lack of confidence in the criminal justice system's ability to protect victims, a perception that due process trumps victims' rights and a decrease in gun legislation spurred the creation of Stand Your Ground laws.
The study cited concerns from law enforcement officials, including doubts that it would deter criminals.
"There must be appreciation among the would-be criminals that deadly force can be used against them, leading to a change in criminal behavior," the study said. "Unfortunately, attendees at the NDAA symposium expressed little confidence that criminals would take the provisions of the Castle Doctrine into consideration before committing a crime."
Webster pointed to a Texas A&M University study examining crime in more than 20 states that passed Castle Doctrine or Stand Your Ground laws from 2000 to 2010. Researchers found that not only was there no decrease in robbery, burglary and aggravated assault, but there was an 8% spike in reported murders and non-negligent manslaughter.
"The data are pretty compelling, showing that it increased justifiable homicides and it increased homicides overall," Webster said. "In all likelihood, it really led to more altercations similar to the Zimmerman-Martin exchange."
