欲加之罪，何患无词yù jiā zhī zuì , hé huàn wú cí

ifyou are out to condemn sb,you can always trump up a charge; give a dog a bad (/an ill) name and hang him; he who has a mind to beat his dogs will easily find his stick; if you want a pretence to whip a dog,say that he ate the frying pan; if you wish to make out a man’s guilt,there is no difficulty in finding ground to do so
❍ 不有废也，君何以兴？欲加之罪，其无辞乎？(《左传·僖十年》)If others had not been removed,how could you have found room to rise? But if you wish to make out a man’s guilt,there is no difficultyin finding ground to do so.
