So no clear idea what they can and cant??
Hypothetically, can CASA legally break into a hangar, jemmy an aircrafts door lock breaking the lock, remove documents and copy them, then leave the hangar wide open to whoever wants to enter and steal, tell no one and deny they were ever there, until the RCA turns???and there's no way they could have gained the information without breaking in, Then still deny they committed larceny.
It happened!!
Same powers as Customs, if you have anything to do with aviation they can, at will, without judicial approval, kick your front door in, terrorise your family while they ransack your home, and leave without so much as a sorry.
These are the powers they have endowed themselves with.
