That second video comes on the heals of two other incidents in downtown Seattle itself:
1) This one had a drone operator fly a quad up to the Space Needle's observation deck level(known to be 500ft AGL), fly two laps around the Needle and then fly down a busy street, taking video footage of the inside of an apartment building until it was spotted by an occupant of one who called police. The operator was able to bring the quad back to his location, pack up and drive away before police arrived
2) A quad was flown around the Seattle "Great Wheel" around dusk. The operator lost control of the quad which then hit the wheel, fell to the ground, smashing a plastic topped table at the restaurant below. The quad is now in the custody of the Seattle Police with word being put out by the local radio and television stations on how it can be claimed.

In the Space Needle incident, the quad was seen by several people on the Needle's outdoor observation deck so verification was provided by multiple people. No verification is needed in the second, considering the quad is presently in the possession of police.
