This might be a silly question, but even if you do fab it 'yourself', does that solve the problem? It might make it harder, but people can still be bribed, or have other pressures applied to them.
I suspect that you're thinking of bribing an organization. You're correct, it's hard to bribe an organization to act against its own interest. But instead, think about bribing one or two workers individuals within the organization. That's much more doable.
