Interesting. I see G4S trucks all the time collecting bank deposits. I always figured they were just another Brinks.

Increasingly G4S operates in “complex environments” and accepts jobs national armies are not trained to do like land mine clearance, and military security in active war zones.

And that is in addition to Black Water which is also involved in Ukraine http://www.telesurtv.net/english/news/Blackwater-Mercenaries-Spotted-in-East-Ukraine-20150421-0042.html

Those security companies could be front companies for governments and corporations to distance themselves from involvement.

They do and they are, but one more thing that does not add up is why he did not use his company equipment and instead bought his own?

If G4S was at the heart of this attack, they would probably want to distance themselves as much as possible from the shooter. Its also possible that they dont let their employees keep their weapons when they're not on a contract.
