As if somebody was going to steal it

Maybe someone can explain the need for this:

"Within minutes of Riar (the pilot) being handed the memo, a scene from a
Hollywood thriller unfolded. White Ford Broncos from the Greater Toronto
Airports Authority zoomed onto the tarmac, encircling his jet and others in
the Jetsgo fleet. The company, as it was doing at airports across Canada,
was safeguarding its biggest assets, 14 Boeing MD-83 and 15 Fokker 100 jets,
an aging fleet of leased and purchased planes."

The plane was parked at the gate.
