Currently, we're not provided with any of these sharp weapons for digging out corruption and malfeasance. Since it's difficult to get thorough evidence, the legal authorities are more careful about what cases they prosecute, and there are more not-guilty verdicts.
目前這些有利於貪瀆案偵破的武器，我們都不具備，所以在證據不易齊全的情況下，法院判起貪瀆罪來就比較審慎，獲判無罪的也比較多。
