In Trump assassination attempt, we need the dog’s story

The initially released surveillance video of the recent attempt to assassinate President Donald Trump was blurry and incomplete. Posted a short time after the incident, it showed Cole Allen, the accused would-be assassin, charging a security site at the April 25 White House Correspondents’ Dinner in Washington. The fuzzy images showed Allen, shotgun in hand, dashing through the metal detectors that had screened people going into the dinner but were then being disassembled. The video did nothing to explain what happened before or after.
