Tennessee lawmaker's somber protest against gun violence.

Rep. Justin Jones, a Democrat, carried an infant-sized casket into Tennessee's Capitol as protesters calling for gun safety legislation outside the Capitol were blocked from bringing caskets inside. Jones was barred from bringing the casket onto the House floor, briefly passing it off at the doorway to fellow Rep. Justin Pearson. The fatal shooting of six people at a Nashville private school last month kicked off a stream of calls for changes to Tennessee’s gun laws, including a ban on assault weapons, tougher background checks and a “red flag” law.
