Why wouldn't he just bribe employees like everyone else does?
Bribery is illegal. This? This is just agents doing agent things, and who can blame them. Agents will be agents.
Bribing employees of private companies as a private person is not illegal(well, maybe it is where you live but I can't know the law everywhere).
private to private bribery is illegal, it doesnt matter if you're private or not. this is true in most EU countries, as well as the US, so I'm unsure where you're from
but corporate bribery (lobbying) is absolutely legal...
