ST. LOUIS, MO (KTVI) – The nation’s gun debate is a hot topic once again.

Defense attorney, Chet Pleban, is here to explain how the mass shooting in Orlando could persuade future decisions made on gun rights cases.

Last week a  federal appeals court ruled, 7-4, that there is no Second Amendment protection for concealed weapons, and that states are allowed to prohibit or restrict you from carrying a concealed firearm.

Pleban believes this case will make it to the Supreme Court. The Supreme Court has only ruled on gun rights a couple times.

D.C. v. Heller, 2008, ruled that individuals have the right to bear arms inside their home, and McDonald v. Chicago, 2010, extended the right to self defense.

Peruta v. San Diego County, which is currently being decided by the 9th Circuit Court, would be particularly interesting if it does make it to the Supreme Court because there would  be a presumptive 4-4 tie.

Pleban believes that public opinion could come into play in a Supreme Court case.
