WOTC - Purchase of weapons

I asked this question in the Wisdom of the Crowd:

Is our purchase of weapons corruption free?

Here are the responses: (47 Votes)

45 % - The corruption takes the form of friendship and hidden incentives
40 % - It is difficult to avoid corruption when the purchases are kept secret.
11 % - I expect the Auditor General Office will carry out the audit.
4 % - I trust that our system will prevent corruption.
