>> right. >> avery, mark's point here about the singularity of what happened in parkland, the incredible horror of that massacre there, there are two ways to interpret this as a one-off or the start of something. >> i think this is the start of something. we look back to october 1, vegas, the deadliest mass shooting in history of the country and the congress and states did nothing. then a few weeks later, a church in texas in sutherland springs where people were massacred at church. i think those two events having happened so close in time to parkland are part of why we are seeing a different reaction now both in florida and in other states and at the federal level. the american people were fed up after vegas, they were fed up after sutherland springs and now they're really fed up. >> there is a three-day waiting period for gun purchases in this, minimum age raised to 21 to buy a firearm.
