Registration Statement on Form S-3

Ladies and Gentlemen:

As General Counsel of The Brink’s Company (the “Company”), I have acted as counsel to the Company in connection with the Registration Statement on Form S-3 (the “Registration Statement”) being filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Act”), on or about the date of this letter, to register 2,260,738 shares of the Company’s common stock, par value $1.00 per share, which may be offered from time to time by The Brink’s Company Master Trust, as set forth in the prospectus contained in the Registration Statement and as may be set forth in one or more supplements to the prospectus (such shares, the “Common Stock”).

I am familiar with the Registration Statement and the exhibits thereto. I, or attorneys under my supervision, have also examined originals or copies, certified or otherwise, of such other documents, evidence of corporate action and instruments as I have deemed necessary or advisable for the purpose of rendering this opinion. As to questions of fact relevant to this opinion, I have relied upon certificates or written statements from officers and other appropriate representatives of the Company and its subsidiaries or public officials. In all such examinations, I have assumed the genuineness of all signatures, the authority to sign and the authenticity of all documents submitted to me as originals. I have also assumed the conformity to the original of all documents submitted to me as copies.

Based upon and subject to the foregoing, I am of the opinion that:

1.	The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the Commonwealth of Virginia.
2.	The shares of Common Stock have been duly authorized and validly issued, and are fully paid and nonassessable.

I hereby consent to the use of my name in the Registration Statement and to the filing, as an exhibit to the Registration Statement, of this opinion. In giving this consent, I do not hereby admit that I am in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Securities and Exchange Commission.

Sincerely,

/s/ McAlister C. Marshall, II
