Hiring club shooter not first blunder for security company

LONDON (AP) — The security company that employed the shooter in the Orlando nightclub massacre has been tarred by a series of blunders and scandals that have raised questions about its competency and ethics.

London-based G4S acknowledged Monday that Omar Mateen, whose rampage left 49 victims dead and more than 50 wounded, worked for the firm at a residential community in South Florida.

Concerns contributed to a 5 percent decline in the company’s stock Monday.

G4S is the world’s largest security company, measured by employees. It has 610,000 workers, including about 50,000 in the U.S, according to its website.

The company provides security for sports and rock stars in addition to 40 U.S. embassies and 32 juvenile-justice detention facilities in the U.S., including 28 residential centers in Florida.
