Dear Sir,
With reference to the enclosed news item, which I understand was successfully terminated tonight by the person being arrested.
My suggestion is this :- Would it not be possible for your organization, on receipt of a demand for money, have on hand a substance which could be sprayed on the money – neutralising the printing after a certain length of time – for example 12 or 24 hours.
Even if the hijacker made a successful landing, his profit would be considerably reduced, if not eliminated. Also the possibility of passing the money through a fence would be very remote.
It would not be necessary that the whole surfaces be sprayed and the [guess: icons] could be held in reserve at the larger cities, where these offences are more prevalent.
Yours Sincerely
