How does ATC prove that someone has entered Bravo airspace?
Radar

While true, radar doesn't seem up to the task for a clip. The three
radar tracks of the Cirrus crash over the East River in NY differ by
enough to convince me that radar could easily indict somebody who was
actually outside the airspace.

Are you talking about the tracks you and many of us saw via online services
or honest to God FAA radar tracks?
